1 Overview of LUN Manager OperationsThis chapter provides a very brief overview of the LUN Manager functions.

• “Overview of LUN Manager” (page 6)

• “Overview of LUN Security” (page 6)Unless otherwise specified, the term storage system in this guide refers to the following disk arrays:

• HP StorageWorks XP24000 Disk Array

• HP StorageWorks XP20000 Disk ArrayThe GUI illustrations in this guide were created using a Windows computer with the Internet Explorerbrowser. Actual windows may differ depending on the operating system and browser used. GUIcontents also vary with licensed program products, storage system models, and firmware versions.

Overview of LUN ManagerLUN Manager provides the open-systems user with ways to define the paths for logical units (LUs).Each LU can be mapped for access from multiple ports, providing the necessary infrastructure tosupport alternative path failover, path load balancing and clustered systems. You can use LUNManager to reconfigure the LUs while the storage system is online so that you can accommodatesystem configuration changes and/or optimize storage system performance.

Overview of LUN SecurityLUN Security provides ways for you to protect mission-critical data in your storage system fromunauthorized access, by preventing unauthorized open-systems hosts from either seeing or accessingthe data on the secured LU.

2 About LUN Manager OperationsThis chapter provides an introduction to Fibre Channel operations, LUN Security, and HPStorageWorks RAID Manager.

• “Overview of LUN Manager Operations” (page 7)

• “ Overview of Fibre Channel Operations” (page 7)

• “Configuring LUN Security” (page 9)

• “Configuring LUs for Use by RAID Manager” (page 10)

Overview of LUN Manager OperationsThe HP storage system can be connected to open-system server hosts of different platforms (forexample, UNIX servers and PC servers). To configure a system that includes open-system hosts anda storage system, you must use LUN Manager to configure logical volumes and ports. Throughoutthis manual, logical volumes are sometimes referred to as LDEVs.One of the important tasks with logical volume configuration is to define I/O paths from hosts tological volumes. If the paths are defined, the hosts can send commands and data to the logicalvolumes and receive data from the logical volumes.After the system begins operating, you might need to modify the system configuration. For example,if hosts or disks are added, you will need to add I/O paths. Even when the system is operating,you can modify the system configuration with LUN Manager. You do not need to reboot the systemwhen changing the system configuration.Use LUN Manager to make various settings with LUs. The settings include the LU path settings.When you configure a system, you must define LU paths to let the hosts transfer data to and fromstorage.It is necessary to change the mode of the HP StorageWorks XP Remote Web Console main windowto the Modify mode to do various settings with LUN Manager. When the background color of theicon on the right of the window is light yellow ( ), the window is in the Modify mode. When thebackground color is gray ( ), it is in the View mode. If you click the ( ) icon when the Unlockedicon ( ) is displayed, the icon changes to ( ) and the mode is changed to the Modify mode.For details on how to change to the Modify mode, see HP StorageWorks XP24000/XP20000Remote Web Console User Guide.

CAUTION: When you define the LU paths, you must not use RAID Manager and Remote WebConsole at the same time.

Overview of Fibre Channel OperationsAfter open-system hosts and the storage system are physically connected by cables, hubs, and soon, you must use LUN Manager to establish I/O paths between the hosts and the logical volumes.This defines which host is able to access which logical volume. Logical volumes that can be accessedby open-system hosts are referred to as logical units (LUs). The paths between the open-systemhosts and the LUs are referred to as LU paths.Before defining LU paths, you must classify server hosts by host groups. For example, if Linux hostsand Windows hosts are connected to the storage system, you must create one host group for theLinux hosts and another host group for the Windows hosts. Then, you must register the host busadapters of the Linux hosts in the Linux host group. You must also register the host bus adapters ofthe Windows hosts in the Windows host group.

Overview of LUN Manager Operations 7

A host group can only contain hosts that are connected to the same port, and cannot contain hoststhat are connected to different ports. For example, if two Windows hosts are connected to port1A and three Windows hosts are connected to port 1B, you cannot register all five Windows hostsin one host group. You must register the first two Windows hosts in one host group and then registerthe remaining three Windows hosts in another host group.After server hosts are classified into host groups, you must associate host groups with logicalvolumes. In “LU Paths Configuration in a Fibre Channel Environment” (page 8), the host grouphg-lnx is associated with three logical volumes (00:00:00, 00:00:01, and 00:00:02). LU pathsare defined between the two hosts in the hg-lnx group and the three logical volumes.

Figure 1 LU Paths Configuration in a Fibre Channel Environment

Use LUN Manager to define paths between a single server host and multiple LUs. In “LU PathsConfiguration in a Fibre Channel Environment” (page 8), each of the two hosts in the host grouphg-lnx is able to access the three LUs.Use LUN Manager to define paths between multiple server hosts and a single LU. In “LU PathsConfiguration in a Fibre Channel Environment” (page 8), the LU identified by the LDKC-CU-LDEVnumber 00:00:00 is accessible from the two hosts that belong to the hg-lnx host group.In “LU Paths Configuration in a Fibre Channel Environment” (page 8), the LUs associated withthe hg-lnx host group are addressed by numbers 0000 to 0002. The address number of an LU isreferred to as LUN (logical unit number). When HP StorageWorks XP Continuous Access Softwareand other program products manipulate LUs, the programs use LUNs to specify the LUs to bemanipulated.

8 About LUN Manager Operations

You can add, change, and delete LU paths when the system is in operation. For example, if newdisks or server hosts are added to your storage system, you can add new LU paths. If an existingserver host is to be replaced, you delete the LU paths that correspond to the host before replacingthe host. You do not need to restart the system when you add, change, or delete LU paths withLUN Manager.If a hardware failure (such as a CHA failure) occurs, there is a chance that some LU paths will bedisabled and some I/O operations stopped. To avoid such a situation, the system administratorcan define alternate LU paths; if one LU path fails, the alternate path takes over the host I/O.For instructions on how to define LU paths, see “Defining Fibre Channel LU Paths” (page 29). Forinstructions on how to change LU path settings, see “Changing the Fibre Channel LU Path Settings”(page 59). For instructions on how to define alternate paths, see “Defining and Viewing AlternatePaths” (page 81).

NOTE:• In a Fibre Channel environment, up to 2,048 LU paths can be defined for one host group.

Up to 2,048 LU paths can be defined for one port.• You cannot define an LU path to volumes reserved by HP StorageWorks XP Auto LUN Software.

For more information about XP Auto LUN, See the HP StorageWorks XP24000/XP20000Auto LUN Software User Guide.

• Up to 255 host groups can be created for one Fibre Channel port.

• You cannot define an LU path to journal volumes.

• You cannot define an LU path to pool volumes.

• You cannot define an LU path to system disk volumes.

• You cannot define an LU path to quorum disk volumes

Configuring LUN SecurityTo protect mission-critical data in your storage system from illegal access, you must apply securitypolicies to logical volumes. Use LUN Manager to enable LUN security on ports to safeguard LUsfrom illegal access.If a port has the External attribute, you cannot apply LUN security to the port.If LUN security is enabled, host groups affect which host can access which LUs. Hosts can onlyaccess LUs associated with the host group to which the hosts belong. The hosts cannot access LUsassociated with the other host groups. For example, hosts in the hp-ux host group cannot accessLUs associated with the windows host group. Also, hosts in the windows host group cannot accessLUs associated with the hp-ux host group.In “Enabling LUN Security” (page 10), LUN security is enabled on port CL1-A. The two hosts inthe hg-lnx host group can only access the three LUs 00:00:00, 00:00:01, and 00:00:02. The twohosts in the hg-hpux host group can only access the two LUs 00:02:01 and 00:02:02. The twohosts in the hg-solar host group can only access the two LUs 00:01:05 and 00:01:06.

Configuring LUN Security 9

Figure 2 Enabling LUN Security

Usually, you do not need to disable LUN security on ports. If LUN security is disabled on a port,the connected hosts will only be able to access LUs associated with host group 0 (zero), and willbe unable to access LUs associated with any other host group.

Figure 3 Disabling LUN Security

The host group 0 is the only host group reserved for each port by default. If you use the LUNManager window to view a list of host groups in a port, host group 0 usually appears at the topof the list and is indicated by the number 00 (see “LU Paths Configuration in a Fibre ChannelEnvironment” (page 8)).By default, the name of host group 0 consists of the port name, a hyphen, and the number 00. Forexample, host group 0 for port 1A is named 1A-G00 by default. Note that you can change thename of host group 0.By default, LUN security is disabled on each port. When you configure your system, you mustenable LUN security on each port to which hosts are connected.For details on how to apply LUN security, see “Using LUN Security” (page 83).

Configuring LUs for Use by RAID ManagerSystem administrators can enter RAID Manager commands from open-system hosts to perform XPContinuous Access and HP StorageWorks XP Business Copy Software operations on logical devices.For example, administrators can enter RAID Manager commands to create or split pairs. To allowthe administrators to use RAID Manager commands, you must ensure that at least one logicaldevice is used as a command device. A command device receives RAID Manager commands

10 About LUN Manager Operations

entered from open-system hosts. When the administrator enters an RAID Manager command froman open-system host, the RAID Manager command is transferred via the command device to thetarget logical device.To protect a logical device from RAID Manager commands, you must apply command devicesecurity to the logical device. If command device security is applied to a logical device, the devicewill not be affected by RAID Manager commands even when commands are transferred via acommand device to that device.For details, see “Configuring the Storage System for Using RAID Manager” (page 84).You cannot use the following volumes as command devices:

• Volumes that do not have Read/Write access attribute

• Volumes reserved by XP Auto LUN. For more information, see HP StorageWorksXP24000/XP20000 Auto LUN Software User Guide.

• XP Continuous Access volumes

• XP Business Copy volumes

• Virtual volumes for HP StorageWorks XP Snapshot Software

• Reserve volumes for Data Retention Utility

• XP Continuous Access Journal volumes

• System disks

• Journal volumes

• Pool volumes

• Remote command device

• Quorum disks

Configuring LUs for Use by RAID Manager 11

3 Preparing for LUN Manager OperationsThis chapter describes the system requirements, instructions for configuring Remote Web Console,enabling the required software, and notes on using LUN Manager.

• “System Requirements” (page 12)

• “Configuring Your Remote Web Console Computer” (page 12)

• “Enabling Required Software” (page 12)

• “Notes on Using LUN Manager” (page 12)

System RequirementsTo use LUN Manager, you need:

• The storage system

• A computer that runs Remote Web Console (Remote Web Console computer)

• A license key for the LUN Manager program productTo use LUN Manager, you must use the Remote Web Console computer to connect to the storagesystem. When you connect, the Remote Web Console program, which is a Java application, willbe downloaded to the Remote Web Console computer. You can perform LUN Manager operationsin the Remote Web Console window.For details about requirements for the Remote Web Console computer, see the HP StorageWorksXP24000/XP20000 Remote Web Console User Guide.

Configuring Your Remote Web Console ComputerLUN Manager operations require the Remote Web Console program, which is downloaded toyour Remote Web Console computer. Your Remote Web Console computer must be connected tothe storage system via a LAN, and requires specific browser settings. If you are able to use RemoteWeb Console, you must install the LUN Manager program product using the license key on theRemoteWeb Console computer. For details about configuring your RemoteWeb Console computer,see the HP StorageWorks XP24000/XP20000 Remote Web Console User Guide.

Enabling Required SoftwareFor details on how to enable LUN Manager, see the HP StorageWorks XP24000/XP20000 RemoteWeb Console User Guide.

Notes on Using LUN ManagerIf you attempt to apply numerous settings in the LUN Manager windows, the storage system mightbe unable to continue processing. HP recommends that you apply no more than 1,000 settings.Several settings are likely to be applied when alternate paths are defined (see “Copying Pathsbetween Fibre Channel Ports” (page 81)), even though only two commands are required for definingalternate paths.

• Do not remove LU paths (see “Deleting LU Paths” (page 80)) when the hosts perform I/Oprocessing.

• Do not disable LUN security (see “Disabling LUN Security” (page 84)) when the hosts performI/O processing.

Launching LUN Manager for Fibre Channel OperationsTo start LUN Manager, take the following steps:1. Start the Web browser.2. Enter the following URL in the Web browser and then press the <Enter> key. The Remote Web

Console login dialog box appears.http://IP-address-of-main-SVP (Web server)

NOTE: If you are unsure of the IP address of the main SVP (Web server), ask the systemadministrator.

3. In the Remote Web Console login dialog box, enter the user name and password and thenclick the OK button.The Remote Web Console main window appears.

4. On the menu bar, click Go, LUN Manager, and then LUN Manager.LUN Manager starts and displays the LUN Manager window.

It is necessary to change the mode of the Remote Web Console main window to the Modify modeto do various settings with LUN Manager. When the background color of the icon on the right ofthe window is light yellow ( ), the window is in the Modify mode. When the background coloris gray ( ), it is in the View mode. If you click the ( ) icon when the Unlocked icon ( ) isdisplayed, the icon changes to ( ) and the mode is changed to the Modify mode. For details onhow to change to the Modify mode, see HP StorageWorks XP24000/XP20000 Remote WebConsole User Guide.

Defining Fibre Channel LU PathsIf you are configuring a Fibre Channel environment, you must take the following four major steps:1. Find WWNs of host bus adapters connected to the Fibre Channel ports (see “Finding WWNs”

(page 30)).2. Create host groups (see “Creating Host Groups” (page 33)).

Launching LUN Manager for Fibre Channel Operations 29

3. Group open-system hosts by host group (see “Registering Hosts in Host Groups” (page 37)).4. Associate host groups with LUs (see “Defining LU Paths by Associating Host Groups to Logical

Volumes” (page 39)).

Finding WWNsIf you are configuring a Fibre Channel environment, you must verify that Fibre Channel adaptersand Fibre Channel device drivers are installed on the open-system hosts. Next, you must find theWWN of the host bus adapter that is used in each open-system host. The WWN is a uniqueidentifier for a host bus adapter in a open-system host, consisting of 16 hexadecimal digits.This section describes how to find the WWN of a host. HP recommends that you make a recordof WWNs of the hosts in your system, because you will need to enter WWNs in LUN Managerdialog boxes to specify the hosts used in your system.

Finding WWN for Windows NT or Windows 2000HP currently supports the Emulex Fibre Channel adapter in a Windows NT or Windows 2000environment, and will support other adapters in the future. For further information on Fibre Channeladapter support, or if you are using a Fibre Channel adapter other than Emulex, contact HPtechnical support for instructions on finding the WWN.To find the WWN in a Windows NT or Windows 2000 environment with an Emulex Mini-PortDriver:

NOTE: Although these instructions are written for Windows NT environment, similar instructionsapply in a Windows 2000 environment.

1. Verify that the fibre adapters and the Fibre Channel device drivers are installed.2. Log in to the Windows NT or Windows 2000 host with administrator access.3. Go to the LightPulse Utility to open the LightPulse Utility/NT window (see “LightPulse Utility/NT

Window” (page 31)). If you do not have a shortcut to the utility, do the following:a. Go to the Start menu, select Find, and then choose the Files and Folders option. The Find

dialog box appears.b. In the Named text field, enter lputilnt.exe.

In the Look in list box, choose the hard drive that contains the Emulex mini-port driver.

c. Choose Find Now to search for the LightPulse utility. If you cannot find the LightPulseutility, contact Emulex technical support.

d. Select lputilnt.exe from the Find: Files named list box, and then press Enter. The LightPulseUtility/NT window opens.

4. In the LightPulse Utility/NT window, the installed adapters are displayed in list box on the leftside of the window. Verify that the installed adapters are displayed.

5. In the LightPulse Utility/NT window, in the Category list box, choose the Configuration Dataoption. In the Region list box, choose the 16 World-Wide Name option. The WWN of theselected adapter is displayed in the list box on the right side of the window.

Figure 21 LightPulse Utility/NT Window

Finding WWN for HP-UXTo find the WWN in an HP-UX environment (see “HP-UX Worldwide Name” (page 32)):1. Verify that the fibre adapters and the Fibre Channel device drivers are installed.2. Log in to the HP-UX host with root access.3. At the command line prompt, type:

/usr/sbin/ioscan -fnC lan

4. This will list the attached Fibre Channel devices and their device file names. Record the FibreChannel device file name (for example, /dev/fcms0).

5. Use the fcmsutil command, along with the Fibre Channel device name, to list the WWN forthat Fibre Channel device. For example, to list the WWN for the device with the device filename /dev/fcms0, type:/opt/fcms/bin/fcmsutil /dev/fcms0

NOTE: When the A5158 Fibre Channel adapter is used, at the command line prompt enter/usr/sbin/ioscan -fnC fc for the device name.

6. Record the Fibre Channel device file name (for example, /dev/td0).

NOTE: When the A5158 Fibre Channel adapter is used, you would list the WWN for thedevice with the device file name as follows:/opt/fcms/bin/fcmsutil <device file name>

7. Record the WWN and repeat the above steps for each Fibre Channel device that you wantto use.

Figure 22 HP-UX Worldwide Name

Finding WWN for SolarisHP currently supports the JNI Fibre Channel adapter in a Sun Solaris environment. This documentwill be updated as needed to cover future adapter-specific information as those adapters aresupported. For further information on Fibre Channel adapter support, or if you are using a FibreChannel adapter other than JNI, contact HP technical support for instructions for finding the WWN.To find the WWN in a Sun Solaris environment:1. Verify that the fibre adapters and the Fibre Channel device drivers are installed.2. Log in to the Sun Solaris host with root access.3. Enter dmesg |grep Fibre to list the installed Fibre Channel devices and their WWNs (see

“Sun Solaris Worldwide Name” (page 33)).4. Verify that the Fibre Channel adapters listed are correct, and record the listed WWNs.


Figure 23 Sun Solaris Worldwide Name

Finding WWN for AIX, IRIX, or SequentTo find the WWN in an AIX, SGI Irix, or Sequent environment, use the fibre switch that is connectedto the host. The method of finding the WWN of the connected server on each port using the fibreswitch depends on the type of switch. For instructions on finding the WWN, see the manual of thecorresponding switch.

Creating Host GroupsYou can connect multiple server hosts of different platforms to one port of your storage system.When configuring your system, you must group server hosts connected to the storage system byhost groups. For example, if HP-UX hosts and Windows hosts are connected to a port, you mustcreate one host group for HP-UX hosts and also create another host group for Windows hosts.Next, you must register HP-UX hosts to the corresponding host group and also register Windowshosts to the other host group.The following procedure describes how to create a host group. The procedure for registering hoststo a host group is described in “Registering Hosts in Host Groups” (page 37).To create a host group:1. Start LUN Manager and display the LUN Manager window (“LUN Manager Window (When

Selecting Icon under Fibre Folder)” (page 13)).2. Right-click the port for which you want to create a host group. Next, select Add New Host

Group from the pop-up menu.The Add New Host Group dialog box (“Add New Host Group Dialog Box” (page 34)) appears.

NOTE: If you right-click an initiator port, you will be unable to select Add New Host Group.You cannot create host groups for initiator ports.

3. Enter the host group name in the Group Name box.It is convenient if you name each host group after the host platform. For example, if you arecreating a host group to register Windows NT hosts in, the host group name can be wnt.A host group name can consist of up to 32 ASCII characters (letters, numerals, and symbols).However, you cannot use the following symbols for host group names:\ / : , ; * ? " < > |

You cannot use space characters for the first and the last characters in host group names.Host group names are case-sensitive. For example, the host group names wnt and Wntrepresent different host groups.


4. Select a host mode from the Host Mode list. When selecting a host mode, you must considerthe platform and some other factors (see “Host Modes for Host Groups” (page 34) for details).

CAUTION:• Do not select Reserve from the list. Reserve indicates that the host mode is not currently

supported.• If the microcode version is updated to 60-08-0X-XX/XX or later, Reserve is not displayed

in the drop-down list. If you set the system option mode 847 to ON, Reserve can bedisplayed in the drop-down list. For details about changing the system option mode, see“Calling HP Technical Support” (page 106).

5. If necessary, click the Option button and then select host mode options (see “Add New HostGroup Dialog Box” (page 34)). For detailed information about host mode options, see “HostMode Options” (page 36).

6. Click OK to close the Add New Host Group dialog box. If a message appears, click OK.The host group name and the host mode are displayed in blue.

7. Click the Apply button in the LUN Manager window.A message appears and asks if you want to apply the setting to the storage system.

8. Click the OK button to close the message.The setting is applied to the storage system.

1 Configure these host mode options only when you are requested to do so.2 Set UUID when you set a host mode option 33 and the host mode 05 OpenVMS is used.3 For using the function of increasing the number of BB Credits, the setting of both the options, host mode options 49

and 50, must be performed.4 Host mode options 49, 50, and 51 are enabled only for 8US package.

Registering Hosts in Host GroupsTo set LU paths, you must register hosts in host groups. For example, if HP-UX hosts and Widowshosts are connected to a port, you must register HP-UX hosts and Windows hosts separately in twodifferent host groups.When registering a host, you are requested to specify the WWN of the host bus adapter. If youare unsure of WWNs of your host bus adapters, see “Finding WWNs” (page 30).When you register hosts in multiple host groups, you must set the security switch (LUN security) toON. When you set the security switch to ON, you must specify the WWN of the host bus adapter.When registering a host, you can assign a nickname to the host bus adapter. If you assign anickname, you will be able to easily identify each host bus adapter in the LUN Manager window.Although WWNs are also used to identify each host bus adapter, the nickname that you assign


will be more helpful because you can name host bus adapters after the host installation site or thehost owners.

NOTE:• A nickname can consist of up to 32 ASCII characters (letters, numerals, and symbols). However,

you cannot use the following characters for nicknames:\ / : , ; * ? " < > |

• You cannot use space characters for the first and the last characters in nicknames.

• Nicknames are case-sensitive. For example, hp and HP are different nicknames.

To register hosts in a host group in a Fibre Channel environment:1. Start LUN Manager and display the LUN Manager window (“LUN Manager Window (When

Selecting Icon under Fibre Folder)” (page 13)).2. If the desired host has ever been connected via a cable to another port in the storage system,

take the following steps:a. Locate the Port list in the upper-right corner of theWWN list. Use this list to select the port

to which the desired host is connected.b. Select the desired host bus adapter from the WWN list. Next, select a host group from

the tree and then click Add WWN.If you are using Windows, you can drag the desired host bus adapter from the WWNlist to the host group in the tree. To drag two or more host bus adapters, see the HPStorageWorks XP24000/XP20000 Remote Web Console User Guide to learn how todrag multiple objects.

c. To assign a nickname to the host bus adapter, enter the nickname in the Name box inthe Add New WWN dialog box (“Add New WWN Dialog Box (When Registering aHost that Has Previously been Connected to the Storage System)” (page 39)), and thenclick OK.If two or more host bus adapters are selected, the Add New WWN dialog boxes (“AddNew WWN Dialog Box (When Registering a Host that Has Previously been Connectedto the Storage System)” (page 39)) appear—one after another to let you assign a nicknameto each of the selected HBAs. If you do not need to assign nicknames to HBAs, you canselect the option The remaining WWNs do not need names and then click OK. If thisoption is selected, the Add NewWWN dialog box (“Add NewWWNDialog Box (WhenRegistering a Host that Has Previously been Connected to the Storage System)” (page 39))will not appear prompting you to assign nicknames.

If the desired host has never been connected via a cable to any port in the storage system,take the following steps:a. In the tree, right-click the host group and then select Add New WWN from the pop-up

menu. The Add NewWWN dialog box (“Add NewWWNDialog Box (When Registeringa Host that Has Never been Connected to the Storage System)” (page 39)) appears.You cannot add WWNs to host groups for initiator ports.

b. Right-click the arrow on the right of the WWN list, and then select the desired host busadapter from the list. If the list does not include the desired host bus adapter, enter thedesired WWN in the WWN list.

c. If necessary, enter a nickname for the host bus adapter.d. Click OK to close the Add New WWN dialog box. If a message appears, click OK.

The specified WWN and nickname appear below the selected host group.


3. Click Apply in the LUN Manager window.A message appears and asks if you want to apply the setting to the storage system.

4. Click the OK button to close the message.The settings are applied to the storage system and the specified host is registered in the hostgroup.

Figure 26 Add New WWN Dialog Box (When Registering a Host that Has Never been Connectedto the Storage System)

NOTE: If the WWN list (located near the lower-left corner of the window) includes a host thatyou want to register, you can register the host by dragging the host from the WWN list to thedesired host group in the tree.

Defining LU Paths by Associating Host Groups to Logical VolumesUse LUN Manager to define LU paths by associating host groups with logical volumes. For example,if you associate a host group consisting of three hosts with logical volumes, LU paths are definedbetween the three hosts and the logical volumes.

NOTE: When you use a logical volume larger than 2 TB, whether the host can access a logicalvolume larger than 2 TB depends on the operating system of the host.

The following operating systems support a logical volume that is larger than 2 TB.

• AIX 5.2 TL08 or later

• AIX 5.3 TL04 or later


• Windows Server 2003 SP1 or later

• Red Hat Enterprise Linux AS 4 Update 1 or laterIf you use other operating system than these, make sure that a logical volume is not larger than 2TB. For information about the maximum value of a logical volume capacity supported by youroperating system, contact the vendor of your operating system.To define LU paths:1. Start LUN Manager and display the LUN Manager window (“LUN Manager Window (When

Selecting Icon under Fibre Folder)” (page 13)).2. In the tree, select a host group.3. From the CU list above the LDEV list, select a CU number.

The LDEV list displays LDEVs in the specified CU image.

4. Select a logical volume from the LDEV list. Next, from the LU Path list, select LUNs indicatedby the icon (this icon indicates a LUN to which no LU path is defined). Next, click the AddLU Path button.A message appears displaying information about LU paths to be defined (“Information aboutLU Paths to be Defined (in Fibre Channel Environment)” (page 40)).

If you are using Windows, you can drag a logical volume from the LDEV list to a LUN ( ) inthe LU Path list. To drag more than one logical volume, see the HP StorageWorksXP24000/XP20000 Remote Web Console User Guide.When you use the LU Path list, you can use the CU list to switch between CU images.

5. Click OK to close the message.The settings are reflected in the LU Path list, but not applied to the storage system yet.


7. Click the OK button to close the message.The settings are applied to the storage system and the LU paths are defined.

Setting Fibre Channel AuthenticationWhen configuring a Fibre Channel environment, you can use the Authentication window(“Authentication Window (When Selecting Fibre Folder)” (page 23) and “Authentication Window(When Selecting Port Icon under Fibre Folder)” (page 26)) to set the user authentication on hostgroups, Fibre Channel ports, and Fibre Channel switches of the storage system.


This section describes the following operations on host groups, Fibre Channel ports, and FibreChannel switches for user authentication:

• Settings and the connection results in authentication of hosts (see “Host and Host GroupAuthentication” (page 43))

• Settings and the connection results in authentication of Fibre Channel switches (see “SwitchAuthentication” (page 46))

• Specifying whether to enable or disable the authentication of hosts in a host group (see“Enabling or Disabling Host Authentication” (page 49))

• Registering user information for hosts on a host group (see “Registering Host User Information”(page 49))

• Changing user information for hosts (see “Changing Host User Information” (page 51))

• Deleting user information for hosts (see “Deleting Host User Information” (page 51))

• Specifying user information for host groups (when performing mutual authentication, see“Registering Host Group User Information” (page 52))

• Clearing user information for host groups (when performing mutual authentication, see “ClearingHost Groups User Information” (page 53))

• Specifying the information for Fibre Channel port (see “Setting Port Information” (page 54))

• Registering user information on a Fibre Channel port (see “Setting Port User Information”(page 55))

• Registering user information on a Fibre Channel switch (see “Setting Switch User Information”(page 56))

• Clearing user information for a Fibre Channel switch (see “Clearing Switch User Information”(page 57))

• Specifying an authentication mode of Fibre Channel switch (see “Setting the SwitchAuthentication Mode” (page 58))

• Specifying whether a Fibre Channel switch can perform authentication (see “Enabling orDisabling Switch Authentication” (page 58))

NOTE: The hosts to be connected also have to be configured for authentication by host groups(and for authentication of host groups by the host, if required). For details on how to configure thehost for CHAP authentication, see the documentation of the operating system and Fibre Channeldriver in your environment.

OverviewWhen configuring a Fibre Channel environment, you can use LUN Manager to set userauthentication between ports of the storage system and hosts. In a Fibre Channel environment, theports and hosts use Null DH-CHAP as the authentication method. This section provides an overviewof user authentication.

NOTE: Throughout this manual, Null DH-CHAP is sometimes referred to as CHAP.

The operation of user authentication in a Fibre Channel environment involves the following threephases:

Setting Fibre Channel Authentication 41

1. A host group of the storage system authenticates a host that attempts to connect (authenticationof hosts).

2. The host authenticates the connection-target host group of the storage system (authenticationof host groups).

CAUTION: Because the host bus adapters currently do not support this function, thisauthentication phase is unusable in the Fibre Channel environment.

3. A target port of the storage system authenticates a Fibre Channel switch that attempts toconnect (authentication of Fibre Channel switches).

The storage system performs user authentication by host groups. Therefore, the host groups andhosts need to have their own user information for performing user authentication.When a host attempts to connect to the storage system, the authentication of hosts phase starts. Inthis phase, it is determined whether the host group requires authentication of the host. If the hostgroup does not require authentication of the host, then the host will connect to the storage systemwithout authentication. If the host group requires it, authentication will be performed for the host.When the host is authenticated successfully, the processing goes on to the next phase.After the authentication of the host succeeds, if the host requires user authentication for the hostgroup that is the connection target, the authentication of host groups phase starts. In this phase,the host groups and hosts authenticate with each other, that is, mutual authentication. In theauthentication of host groups phase, if the host does not require user authentication for the hostgroup, the host will connect to the storage system without authentication of the host group.The following explains the settings required for user authentication. The settings for authenticationof host groups are needed only when you want to perform mutual authentication.

• Settings for authentication of hostsOn the storage system:Use LUN Manager to specify whether to perform authentication of hosts on each hostgroup. On a host group that performs authentication, register user information (group

◦

name, user name, and secret) of the hosts that are allowed to connect to the host group.A secret is a password used in CHAP authentication. When registering user information,you can also specify whether to enable or disable authentication on a host basis. Fordetails on the settings, see “Enabling or Disabling Host Authentication” (page 49) and“Registering Host User Information” (page 49).

◦ On hosts:Configure the operating system and Fibre Channel host bus adapter driver forauthentication by host groups with CHAP. You need to specify the user name and secretof the host used for CHAP. For details, see the documentation for the operating systemand Fibre Channel host bus adapter driver in your environment.

• Settings for authentication of ports (required if performing mutual authentication)On the storage system:Use LUN Manager to specify user information (user name and secret) of each host group.

◦

◦ On hosts:Configure the operating system and Fibre Channel host bus adapter driver forauthenticating host groups with CHAP. You need to specify the user name and secret ofthe host group that is the connection target. For details, see the documentation for theoperating system and Fibre Channel host bus adapter driver in your environment.

When authentication of a host succeeds, the host performs authentication of the port reversely ifrequired by the host (mutual authentication). In authentication of ports, when the user information


(user name and secret) of the port specified on the port side matches that stored on the host, thehost allows the host group to connect.

Host and Host Group AuthenticationWhen a host attempts to connect to the storage system, the connection results of the authenticationof the host differs depending on the host group settings. “Flow of Authentication of Hosts (In a FibreChannel environment)” (page 43) illustrates the relationship between host group settings and theconnection results in a flow.

Figure 28 Flow of Authentication of Hosts (In a Fibre Channel environment)

Each case in the flow is explained as follows. Case A to Case D in “Flow of Authentication of Hosts(In a Fibre Channel environment)” (page 43) corresponds that below.

• When performing authentication of host groupsIf the user information for the host is registered on the host group, and authentication ofthe host is enabled (Case A):The host group authenticates the user information sent from the host. If the authenticationof the host successes, either of the following actions occur:

◦

– When the host is configured for mutual authentication, the processing will go on toauthentication of the host group, next.

– When the host is not configured for mutual authentication, the host will connect tothe storage system.


If the host is not configured for authentication by host groups with CHAP, the authenticationfails and the host cannot connect to the storage system.

◦ If the user information for the host is registered on the host group, but authentication ofthe host is disabled (Case B):The host group does not perform authentication of the host. The host will connect to thestorage system without authentication, regardless of whether or not the host is configuredfor authentication by host groups with CHAP.

◦ If the user information for the host is not registered on the host group (Case C):Irrespective of the setting on the host, the host group performs authentication of the host,but results in failure. The host cannot connect to the storage system.

• When connecting via a host group that does not perform authentication of hosts (Case D):The host will connect to the storage system without authentication of the host, regardless ofwhether or not the host is configured for authentication by host groups with CHAP.In this case, you need not register the user information for the host on the host group, but youcan register it.

Notes: You should register user information for all hosts to be connected to a host group thatperforms authentication of hosts. To allow a specific host to connect to such a host group withoutauthentication, configure the host group and the host as follows:On the host group: Register the user information for the host you want to allow to connect withoutauthentication, and then, disable the authentication setting of the host.“Example of Authentication of Hosts” (page 45) shows an example of authentication of hosts. Inthis figure, WWNs of host bus adapters (HBAs) are abbreviated as a, b, and so on.


Figure 29 Example of Authentication of Hosts

In “Example of Authentication of Hosts” (page 45), host group 1 performs authentication of hosts,but host group 2 does not.The user information for Host A is registered on host group 1, and the authentication setting isenabled. Therefore, if authentication of the host is successful, Host A can connect to the storagesystem (or, the processing goes on to the authentication of the host group). As a precondition ofsuccessful authentication, Host A should be configured for authentication by host groups withCHAP.The user information for Host B is also registered on host group 1, but the authentication setting isdisabled. Therefore, Host B can connect to the storage system without authentication.The user information for Host C is not registered on host group 1. Therefore, when Host C tries toconnect to the storage system, the authentication fails and the connection request is denied,regardless of the setting on Host C.Host D is attached to host group 2, which does not perform authentication of hosts. Therefore, HostD can connect to the storage system without authentication.During authentication of hosts, the connection result is determined by the combination of thefollowing host group settings:

• Setting of the host group in the Port tree: enable ( ) or disable ( )

• Whether or not the user information for the host that attempts to connect is registered on thehost group


“Combinations of port settings and connection results” (page 46) shows the relationship betweenthe combinations of host group settings and the connection results in authentication of hosts.Regardless of whether or not the host is configured for authentication by ports with CHAP, theconnection results are as follows, unless otherwise noted.

to connect to the port without authentication, do not configure it for authentication by ports with CHAP.

Switch AuthenticationWhen a host attempts to connect to the storage system, the connection results of the authenticationof the Fibre Channel switch differ depending on the Fibre Channel switch setting related to eachport. “Flow of Authentication of Fibre Channel Switch” (page 47) illustrates the relationship betweenFibre Channel switch settings and the connection results in a flow. The setting of Fibre Channelswitch authentication is independent from the setting of host authentication.


Figure 30 Flow of Authentication of Fibre Channel Switch

Each case in the flow is explained as follows. Case A to Case D in “Flow of Authentication of FibreChannel Switch” (page 47) corresponds that below.

• When performing authentication of Fibre Channel switches by ports:If the user information for the Fibre Channel switch is registered on the port, andauthentication of the Fibre Channel switch is enabled (Case A):Each port authenticates the Fibre Channel switch. If the authentication of the Fibre Channelswitch ends successfully, either of the following actions occurs:

◦

– When the Fibre Channel switch is configured for mutual authentication, the processingwill go on to authentication of the port, next.

– When the Fibre Channel switch is not configured for mutual authentication, the FibreChannel switch will connect to the storage system.


If the Fibre Channel switch of the port is not configured for authentication with CHAP,the authentication fails and the Fibre Channel switch cannot connect to the storage system.

◦ If the user information for the Fibre Channel switch is registered on the port, butauthentication of the Fibre Channel switch is disabled (Case B):The ports do not perform authentication of the Fibre Channel switch. The Fibre Channelswitch will connect to the storage system without authentication regardless of whether ornot the Fibre Channel switch is configured for authentication with CHAP.

◦ If the user information for the Fibre Channel switch is not registered on the port (Case C):Regardless of the setting on the Fibre Channel switch, the port performs authenticationof the Fibre Channel switch, but results in failure. The Fibre Channel switch cannot connectto the storage system.

• When not performing authentication of Fibre Channel switches by ports (Case D):The Fibre Channel switch will connect to the storage system without authentication of the host,regardless of whether or not the Fibre Channel switch is configured for authentication withCHAP.In this case, you need not register the user information for the Fibre Channel switch on theport, but you can register it.

During authentication of hosts, the connection result is determined depending on the combinationof the following port settings:

• Setting of the port in the Port tree: enable ( ) or disable ( )

• Whether or not the user information for the Fibre Channel switch that attempts to connect isregistered on the port

“Combinations of Fibre Channel settings and connection results” (page 48) shows the relationshipbetween the combinations of port settings and the connection results in authentication of FibreChannel switches.

Authentication of Ports (Performing Mutual Authentication)When authentication of a host succeeds, the host performs authentication of the port if requiredby the host (mutual authentication). In authentication of ports, when the user information (user name


and secret) specified on the port side matches that stored on the host, the host allows the hostgroup to connect.

Configuring Fibre Channel Authentication

Enabling or Disabling Host AuthenticationYou can specify whether or not to perform authentication of hosts on each host group.

4. Select an address from the Fibre Addr. list in the Mode area.5. Click the Set button.

A message appears and asks if you want to change the port settings.




Setting the Fibre Channel TopologyThe term topology indicates how devices are connected to each other. Fibre Channel provides thefollowing types of topology:

• Fabric: Utilizes a fabric switch to connect a large number of devices (up to 16 million) together.Each device will have the full bandwidth of 100 MB/sec.

• FC-AL (Fibre Channel-Arbitrated Loop): Shared interface that can connect up to 126 devices(AL-ports) together. The 100 MB/sec bandwidth is shared among the devices connected toeach other.

• Point-to-point: The simplest fibre topology connects two devices directly together.

Figure 42 FC-AL Topology and Point-to-point Topology

When you configure your system, you must use the LUN Manager window to specify whether thehosts and the storage system are connected via a fabric switch.


If a fabric switch is used, specify FC-AL or point-to-point in the LUN Manager window (by default,FC-AL is specified). If a fabric switch is used, consult the documentation for the fabric switch tolearn whether FC-AL or point-to-point should be used. Some fabric switches require you to specifypoint-to-point to get the system running.If no fabric switch is used, you must specify FC-AL.To specify the topology:1. Start LUN Manager and display the Port window (“Port Window (When Selecting Icon under

Fibre Folder)” (page 19)).2. In the Package tree, select the Fibre folder or a channel adapter of Fibre Channel (“Port

Window (When Selecting Icon under Fibre Folder)” (page 19)).• If you select the Fibre folder, the Port list displays a list of Fibre Channel ports in the




4. If a fabric switch is used, select Enable from the Fabric list in the Mode area.If a fabric switch is not used, select Disable from the Fabric list in the Mode area.

5. Select FC-AL or P-to-P from the Connection list.

NOTE: If a fabric switch is used, consult the documentation for the fabric switch to check ifyour fabric switch requires the point-to-point topology. Some fabric switches require thepoint-to-point topology to get the system running. To specify point-to-point topology, selectP-to-P.

6. Click the Set button.A message appears and asks if you want to change the port settings.




CAUTION: When you change the settings while you are online to the hosts, the device may notbe recognized from the hosts. In this case, you will need to reboot the hosts.

Changing the Fiber PCB Mode Between Standard, High Speed, and Initiator/ExternalMix Mode

Channel adapter boards have built-in ports to be used for connecting hosts and a storage system.The ports can be in Standard mode, High Speed mode, or Initiator/External MIX mode, thoughall the ports are in Standard mode by default. If a port satisfies certain conditions, you can applyHigh Speed mode to the port to improve port performance. Or, if a port satisfies certain conditions,you can apply Initiator/External MIX mode so that one port can be used as both an initiator portfor XP Continuous Access or XP Continuous Access Journal and an external port applied to a remotecommand device. For more information on how to define the remote command device, see the HPStorageWorks XP24000/XP20000 External Storage Software User Guide.


You must apply High Speed mode or Initiator/External MIX mode to groups of four ports, not toindividual ports. In LUN Manager terminology, each group of four ports is referred to as a portblock. You can apply High Speed mode or Initiator/External MIX mode to each port block.When you apply High Speed mode or Initiator/External MIX mode, each pair of ports in a portblock must satisfy the following conditions.

• The two ports take the same fabric option (Enable or Disable).

• The two ports take FC-AL as the Connection option.

• The two ports use different port addresses and no matching addresses.

• When you apply High Speed mode, the two ports take the same port attribute (the attributecan be Initiator, RCU target, or Target).

• When you apply Initiator/External MIX mode, one port takes the Initiator attribute and theother port takes the External attribute.

• Only one port is to be used for connecting the host.“Ports in High Speed Mode or Initiator/External MIX mode” (page 69) shows an example of HighSpeed mode or Initiator/External MIX mode applied to one or two port blocks when the channeladapter board has 8 ports.


Figure 43 Ports in High Speed Mode or Initiator/External MIX mode

If High Speed mode is applied to the four ports in a port block, only two of the ports can be usedfor connecting the host. When hosts issue I/Os to ports, the I/Os will be processed by processorson channel adapters. I/Os to each port will be processed by only one processor in Standardmode, but by two processors in High Speed mode. Therefore, ports in High Speed mode canprocess I/Os faster than ports in Standard mode. By balancing the workloads on the processors,a greater improvement can be expected with the system performance.You cannot change standard mode to high-speed mode or vice versa while you are online to thehosts. You will need to reboot the hosts after changing the mode.To change the configuration of a port that is being used, you must perform a backup operationbefore changing the port configuration.Port names can differ, depending on whether ports are in Standard mode, High Speed mode, orInitiator/External MIX mode. For detailed information about port names, see tables later in thissection.


To improve the I/O processing speed by applying High Speed mode, a path definition is alsonecessary for a port that cannot be used for the connection with a host. For example, if the modeof the port block including the CL1-A port is changed to High Speed, the path definition is alsonecessary for the CL3-A [1-A 2nd] port that cannot be used for the connection with a host.

NOTE:• Sometimes the Standard mode, the High Speed mode, and the Initiator/External MIX mode

are collectively referred to as Fibre PCB modes. PCB is an acronym for printed circuit board.The storage system documentation sometimes uses the term PCB when referring to a channeladapter, which is a printed circuit board used for connecting hosts and a storage system.

• Storage partition administrators cannot apply the High Speed mode or the Initiator/ExternalMIX mode.

Viewing a List of Concatenated Parity GroupsThe storage system supports concatenation of parity groups. If parity groups are concatenated, alogical volume can be dispersed across the concatenated parity groups. Dispersal of logical volumescan provide faster access to data (particularly, faster sequential access to data).

NOTE: Only an HP service representative can concatenate parity groups. If you have any questionsabout concatenation of parity groups, ask your HP service representative.

You can confirm whether a logical volume is dispersed across two or more parity groups. If thelogical volume is dispersed across parity groups, a dialog box appears and displays a list of theparity groups.

Viewing a List of Concatenated Parity Groups 79

To view a list of concatenated parity groups:1. Start LUN Manager and display the LUN Manager window (“LUN Manager Window (When

Selecting Icon under Fibre Folder)” (page 13)).2. In the LDEV list, select a logical volume (that is, an LDEV) and then right-click the selected

volume.3. Check to see if the Concatenation List command appears in the pop-up menu.

• If the Concatenation List command appears, the logical volume is dispersed across paritygroups. Select Concatenation List to view a list of the parity groups (“Concatenation ListDialog Box” (page 80)).

• If the Concatenation List command does not appear, the logical volume is not dispersedacross parity groups.

Figure 45 Information about LU Paths to be Deleted

NOTE: If you delete numerous paths at one time, the deletion may take time and the dialog boxmay seem to hang temporarily.

Defining and Viewing Alternate PathsLUN Manager enables you to define alternate paths. If one LU path fails, you can switch to itsalternate path.To create an alternate path, you need to copy the original path from one port to another. Forexample, if you want to define an alternative for the LU path from the CL1-A port to the logicalvolume 00:00 :01, you need to copy the LU path from the CL1-A port to another port.

Copying Paths between Fibre Channel PortsTo use alternate paths, you must copy LU paths from one port to another.

CAUTION:• Before taking the following steps, see “Notes on Using LUN Manager” (page 12) for important

information.• To define alternate paths when LUN security is disabled, you must redefine the LU path.

To define alternate paths:1. Start LUN Manager and display the LUN Manager window (“LUN Manager Window (When

Selecting Icon under Fibre Folder)” (page 13)).2. In the tree, double-click the copy source port to display host groups below the port.3. To copy all the LU paths defined in a host group, take the following steps to copy the host

group:a. Right-click the host group in the tree.

NOTE: If you right-click a host group for an initiator port, you cannot copy paths.

b. Select Copy from the pop-up menu.The selected host group turns green.

Using LUN SecurityTo protect mission-critical data in your storage system from illegal access, you need to secure thelogical volumes in the storage system. Use LUN Manager to secure LUs from illegal access byenabling LUN security on ports.By default, LUN security is disabled on each port. When configuring your system, you must enableLUN security on ports.If a port has the External attribute, you cannot apply LUN security to the port.When you register hosts in multiple host groups, you must set the security switch (LUN security) toON. When you set the security switch to ON, you must specify the WWN of the host bus adapter.

Enabling LUN Security

NOTE: If a port has the External attribute, you cannot apply LUN security to the port.

To enable LUN security on a port:1. Start LUN Manager and display the LUN Manager window (“LUN Manager Window (When

Selecting Icon under Fibre Folder)” (page 13)).2. In the tree, locate the desired port.3. See the text on the right of the port name to find LUN security status:

Configuring the Storage System for Using RAID ManagerThe system administrator can enter RAID Manager commands from open-system hosts to performXP Continuous Access and/or XP Business Copy operations on logical devices. For example, RAIDManager commands can be used to create and split pairs. To enable the system administrator toenter RAID Manager commands from open-system hosts, you must specify at least one logicaldevice as the command device. You can also apply command device security to other logicaldevices in the storage system.

NOTE: If a storage system is divided into SLPRs, and you want to prevent RAID Managercommands from affecting multiple SLPRs, you must apply command device security to the logicalvolumes.

Specifying Logical Devices as Command DevicesTo enable the system administrator to execute RAID Manager commands from an open-systemhost, you must select at least one logical device that will not be manipulated by XP ContinuousAccess or XP Business Copy, and then specify the device as the command device. When an RAIDManager command is issued from a host, the command is received by the command device. Thecommand device transfers the command to another logical device. Then, the command performsan XP Continuous Access or XP Business Copy operation on that logical device.To specify a logical device as a command device:



2. In the upper-right LU Path list or the lower-right LDEV list, select and right-click the desiredlogical device.

• If nothing is displayed in the LU Path list, select a host group in the tree.

• The icon indicates no logical device.3. From the pop-up menu, select Command Device: Disable -> Enable.

A message appears, asking if you want to use the logical device as a command device.




Deleting Command DevicesTo delete a command device:1. Start LUN Manager and display the LUN Manager window (“LUN Manager Window (When

Selecting Icon under Fibre Folder)” (page 13)).2. In the upper-right LU Path list or the lower-right LDEV list, select and right-click a command

device ( or ).3. From the pop-up menu, select Command Device: Enable -> Disable.

A message appears.




Enabling Command Device SecurityTo protect logical volumes from RAID Manager commands, you must apply command devicesecurity to the logical volumes. If command device security is applied to a logical device, the logicaldevice will not be affected by RAID Manager commands issued via command devices from thehosts.To apply command device security to a logical device:1. Start LUN Manager and display the LUN Manager window (“LUN Manager Window (When

Selecting Icon under Fibre Folder)” (page 13)).2. In the upper-right LU Path list or in the lower-right LDEV list, select and right-click the desired

command device.• If nothing is displayed in the LU Path list, select a host group in the tree.

(page 88)), enter a UUID in the UUID box. If a UUID is already specified in the UUID box,you can change it. However, if multiple LUNs, or N/As are selected, the UUID box is blank.• For an OpenVMS server host, use a numerical value from 1 to 32,767 (see “Set UUID

Window (When a OpenVMS Server Host is Used)” (page 87)).• For a server host other than OpenVMS, use up to 64 ASCII characters (letters, numerals,

and symbols) for a UUID (see “Set UUID Window (When a Server Host Other ThanOpenVMS is Used)” (page 88)). The following rules apply to UUIDs:◦ The following characters cannot be used for UUIDs:

\ / : , ; * ? " < > |

◦ A space character cannot be used for the first and the last characters of a UUID.

◦ UUIDs are case-sensitive. For example, hp and HP are different UUIDs.

NOTE: Definition informations about devices set by LUN Manager are very importantinformation to configure the system (for example, LUNs, LDKC:CU:LDEV, or UUID). HPrecommends that you to make a correspondence table such as “An Example of aCorrespondence Table for Definition Informations About Devices” (page 87).When changing the server host OS from HP-UX to Open VMS, or from Open VMS to HP-UX,the same UUID cannot be used continuously. Clear the setting of UUID, and then set the properUUID for a server host, respectively. For more informations about clearing the setting of UUID,see “Clearing the setting of UUID” (page 88).

Function TagsBefore you write the settings, you need to state the function of the parameter. This is called afunction tag, which is formatted as a string in brackets ([ ]). The type and order of the function tagare determined by the program product. Function tags have the following characteristics:

• At least one function tag is required in a spreadsheet.

• The function tag must be written at the very beginning of the row.

• If a function tag is already on the current spreadsheet and does not need to be changed, itmust be deleted from the new spreadsheet so it is not processed. If the function tag remainsin the spreadsheet, and no new settings for the tag are written, the settings are processed asdeleted. [CHA], [Port] and [LDEV] tags do not support a delete operation, so if no new settingis written for these functions an error occurs.

• Any other comments and settings written in the same row as the function tag are ignored.


• The row after the function tag indicates the required setting items (Cha and PcbMode in theexample) for the function. The setting items are separated by commas.◦ Example:

[Cha]

#Cha, PcbMode

• The existing settings for the function are written. The existing settings row, which starts with#$, is recognized as a comment row.

CAUTION: The settings in the rows that start with #$ are not allowed to change.

◦ Example:[LUN]

#Port, Group Id, LunId, Ldkc, Cu, Ldev (items to be changed)#$1C,0,1,1,1,1 (existing settings row)

• An example of the declaration and the function tag is as follows.#!Version 05_00_00,LUN,Change

[Cha]

[Port]

[HostGroup]

[WWN]

[LUN]

[LDEV]

As a general rule , the settings are applied to the storage system one at a time, in the order theyappear in the spreadsheet. This means that the settings of the prior function tags can affect thefollowing function tags. For example, if you were to delete a host group in the [HostGroup] tag,the path settings related to the deleted host group would also be automatically deleted. If you thenwrite the new settings for the automatically deleted path in the [LUN] tag or the [WWN] tag, anerror would occur.

Configuration DefinitionsThere are three types of configuration definitions: adding new settings, deleting current settings,and changing current settings.

• Adding new settings. You can add new settings if the current settings area of the spreadsheetis blank (see “Sample Configuration Definitions” (page 94)).

• Deleting current settings. You can delete existing current settings by making the new settingsarea blank.

• Changing current settings. You can change existing current settings by writing a differentsetting in the new settings area. The format of the existing setting and the new settings mustbe the same

The configuration definition consists of the index and the parameter (see “Sample Index andParameter Definitions” (page 94)). The index is fixed for each function tag, so it must be the samefor both the current settings and the new settings. By modifying the settings in the parameter, youcan add, delete, or change the settings.You can write the configuration definition either between a function tag and another function tag,or between a function tag and the end of the file. Using a configuration definition, you can set the

Spreadsheet Components 93

parameters (adding, deleting, or changing) for the storage system. A row of configuration definitionscan be divided into the current settings area, a blank column, and the new settings area.Configuration definition settings must comply with the following:

• The current settings area and the new settings area must be in exactly the same format, withthree blank columns in between.

• The maximum number of columns for the settings depends on the program product, and isstated in the declaration row.

• The number of the available columns for each function tag depends on the number ofparameters that can be set for each function and on the version of the spreadsheet.

• When the current spreadsheet file is downloaded, the new settings area is left blank. All ofthe columns should be separated by commas.

• You may not change the indexes, and all of the specified index settings indexes must matchthe actual settings.

• Do not write the identical index more than once in the same function tag.

• To change some, but not all, of the settings on the same configuration definitions, you mustcopy and paste the settings that you do not want to change to the new settings area. Otherwise,those settings will be processed as deleted.

“Sample Index and Parameter Definitions” (page 94) shows an example of index and parameterdefinitions.

Figure 51 Sample Index and Parameter Definitions

“Sample Configuration Definitions” (page 94) shows sample configuration definition settings.

Figure 52 Sample Configuration Definitions


CommentsYou can also type comment rows in the spreadsheet by beginning a row with the # character. Thecomment row can consist of any characters in any language. A row that includes only a linefeedcode is also recognized as a comment row.

• Example:# (comment)# Change CHA settings (comment)[Cha](function tag)# Cha, PcbMode (comment)# (linefeed)# (linefeed)CHA-1P,Standard (indicating changes)CHA-1Q,Standard (indicating changes)

LUN Manager Spreadsheet SettingsThe following LUN Manager functions can be defined by using Configuration File Loader:

• Channel Adapter (CHA) settings allow you to change the PCB mode. See “Setting the CHAMode” (page 96).

• Port Settings allow you to change the settings for arbitrated loop-physical address (AL-PA),data transfer speed (host speed), and topology. You can also change the LUN Security setting.See “Port Settings” (page 97).

• Host Group Settings allow you to create, delete, or change the host group. See “Setting theHost Group” (page 98).

• WWN settings allow you to add, delete or change the WWN information. See “Setting theWWN Information” (page 100).

• LU path settings allow you to add, delete, or change LU paths. See “Setting the LU Path”(page 101).

• Command Device settings and set or release the command device and command devicesecurity. See “Configuring the Command Devices” (page 102).

Column FormatUse a LUN Manager spreadsheet to write the settings for the CHA mode, port, host group, WWN,path definition, and command devices. The format of the LUN Manager spreadsheet is as follows:

• 1st column to 7th column: Current settings area

• 8th column to 10th column: Blank columns

• 11th column to 17th column: New settings areaThe number of columns used depends on the function tag. If a particular function tag requires lessthan seven columns, the unused columns are left blank.“LUN Manager Spreadsheet Format” (page 96) describes the format of the LUN Managerspreadsheet.

Setting the CHA ModeUse the [CHA] tag to set the channel adapter mode. The [CHA] tag is available only for changingsettings. You cannot add or delete the settings with the [CHA] tag definitions.Mainframe settings are not written on the exported spreadsheet. If you are using 8 Gbps settings,you cannot set HighSpeed for the PCB mode. When you want to set the initiator/external mixmode for the PCB mode, set HighSpeed just as when you set the high speed mode.“Available Configuration Values for the [CHA] Tag” (page 97) lists the available configurationdefinitions for the [CHA] tag.

Setting the Host GroupUse the [HostGroup] tag to add, delete, or change the host group information. The followingparameters apply:

• You can delete the settings for host group 0 (zero), but the host group itself cannot be deleted.If you delete all the settings for host group 0, the settings revert to the default settings.

• When you delete a host group, the WWN and path definition of that host group areautomatically deleted. Therefore, if you write the settings for a host group that is deleted inthe [LUN] tag or [WWN] tag, an error occurs.

“Available Configuration Values for the [HostGroup] Tag” (page 99) lists the items and valuesavailable for the [HostGroup] tag.

“Concept of Host Mode Option” (page 100) shows the concept of the host mode option. The hostmode option consists of 96 flags, which are from 0 to 95. The host mode option is stored bydividing 32 flags. “Concept of Host Mode Option” (page 100) illustrates these flags as the optionflag ID from 0 to 31. The binary bit flags (option flags) are given to each ID (starting with 0), andevery four binary bit flags are set as a group to be converted to the hexadecimal number thatfinally represents the host mode option.“Example of Host Mode Option” (page 100) shows an example of the host mode option. In thecase of “Example of Host Mode Option” (page 100), the host mode option becomes 1AB30005.For the binary to the hexadecimal conversion, see “Binary to Hexadecimal Conversion” (page 100).The host mode option should be written in one digit or more (up to eight digits). 0s at the head ofthe number can be omitted when you set the value. For example, 00000FE3 can be written asFE3. The default value when the spreadsheet is exported is written in eight digits.

Configuring the Command DevicesUse the [LDEV] tag to change the command device settings. You cannot add or delete commanddevice settings with the [LDEV] tag definitions.When the command device (Cmd .Dev) is OFF, and the command device security (Cmd. Sec) isON, an error occurs.You can set the command device OFF, regardless of the existence of the LU path.When you want to configure the setting of a remote command device, add #$ at the beginningof the row. If you do not add #$, an error occurs.You can save a file that contains LDEV information in the comma-separated value (CSV) format byusing the Export button on the LDEV window of the Reports Display dialog box. You can set thecommand device by using this file. However, because the output form is different from the form ofthe configuration definitions, colons (:) that delimit the LDKC number, CU image number, andlogical volume number have to be converted to commas (,). Use this information after you usecommas to separate the LDEV index into three columns and when you use the spreadsheet software.“Available Configuration Values for the [LDEV] Tag” (page 103) lists the values available for the[LDEV] tag.

Error Check

First Error CheckThe first error check is performed when the spreadsheet file is imported. The first error check verifiesthat the spreadsheet is properly formatted. If there is an error, the spreadsheet is rejected, and anerror message is displayed. Errors detected at this first check include the following:

• The first row of the spreadsheet (the declaration line) is not correctly written, or the statedprogram product is not installed. For more information on the declaration line, see “SpreadsheetDeclaration” (page 92).

• The spreadsheet file is not in text file format (the file is a binary file).

• There is no function tag in the spreadsheet. For more information on the function tag, see“Function Tags” (page 92).

• The file name is incorrect (for example, the extension is not .spd, or the file name exceeds themaximum number of letters).

• The number of letters in a row exceeds 200.

• The number of rows in a spreadsheet exceeds 400,000.

Error Check 103

Second Error CheckIn the second check, the spreadsheet settings are verified. Any errors found are displayed on theError Information list. This second check is performed before the Apply button becomes available.“Second Error Check Flow Chart” (page 105) shows the flow of the second check.The second error check consists of two different types of the checks. These checks are shown in“Second Error Check Flow Chart” (page 105) as the Level 1 and Level 2. The Level 2 check isperformed only when no error is found by the Level 1 check. Each level of the check of the seconderror check detects the following errors:

• Level 1 check (the format and parameters are checked):A function tag is not supported.◦

◦ A setting value is incorrect or omitted.

◦ The setting range is incorrect. The correct ranges are as follows:LDKC:00CU:00 - FELDEV:00 - FFLUN: 0000 - 07FFGroup ID: 00 - FEHost Mode: 00 - 4F

• Level 2 check:The current settings are compared to the imported settings and checked for logical consistency.Note that certain errors can only be detected by the third check.

When you import a spreadsheet with no errors detected, the window displays Ready above theerror information list, and the Apply button becomes available.


Figure 55 Second Error Check Flow Chart

Third Error CheckThe third check is performed after the Apply button is selected. Errors detected at this third checkinclude the following:

• There is no difference between the current configuration definition and the configurationdefinition on the imported spreadsheet. The spreadsheet is accepted, but no operation willbe performed.

• You are trying to delete a LUN that is needed to process input/output (I/Os).The errors caused by other factors are detected by the second check as the logical errors of thesettings. However, there could be a case where the current settings are changed even though youare on the Modify mode. In this case, an error occurs at the third check.If no errors are found on the third error check, the settings in the spreadsheet are applied to thestorage system.
