Lab Exercise 3: Symmetrix Array Configuration

Purpose:

To create storage volumes of a specified configuration on a Symmetrix

array and map them to Front-End ports.


Identify Symmetrix with unconfigured capacity.

Create Symmetrix Logical Volumes using ControlCenter or

Symmetrix Management Console.

Map Symmetrix Logical Volumes to Front End Director Port

using ControlCenter.

Create Symmetrix Meta Volumes.

Change Symmetrix Device Type Definitions.

References: Module 5: Configuration and Control

Appendix: Symmetrix Management Console (Optional)




Part 1 A: Create Logical Volumes

Creating Symmetrix logical volumes or devices can be accomplished using the menus and

dialogues discussed in Lab Exercise 3, Symmetrix Array Configuration. Part 1A uses the traditional ControlCenter Device Configuration context sensitive menus to create Symmetrix

devices. Part 1B uses the traditional ControlCenter context sensitive menus to launch

Symmetrix Management Console (SMC) and create Symmetrix devices. Perform either

Part 1A or Part 1B.

Step Action

Note It is recommended to perform Lab Exercise 3, Part 1A because you will use the

procedures in Part 1B to create Symmetrix “Thick” and “Thin” Provisioning.

1 Investigate the Current Environment.

Select Properties from the Tool Bar and then select Storage Systems from the Tree Panel.

Look for the Unconfigured Capacity column in the Target Panel.

Is there Unconfigured Capacity available on the Symmetrix assigned to your lab group (the

Symmetrix attached to your assigned host)? Record the Symmetrix Serial

Number:_____________, Unconfigured Capacity: _________________

2 Use the Masking and Properties views to examine the Symmetrix devices masked to your

host. Use this information to find the typical data device size—the most frequently used

size, not including gatekeeper or VCMDB devices. You will be creating new devices to

match this size.

Typical data device size (MB): _________________

3 Identify the Primary Symmetrix Agent for your assigned Symmetrix. Select Agents from the

ECC Administration drop down menu. Then select your assigned Symmetrix from the

Tree Panel. The primary agent can be identified in the tabular agents view, look for “Yes”

under the Is Primary? column and correlate this with the Responsible for Objects column.

<continued>



Step Action

4 Create Four Symmetrix Logical Volumes.

a) Right-click your assigned Symmetrix and select Device Configuration Logical

Device Configuration. Wait till the configuration lock is acquired, and click OK at the

warning.

b) In the Logical Device Configuration window, and create four, two-way mirrored

devices of the typical size you determined above. Make sure you record the numbers of

your new devices: _____________________________________

c) After successful completion, verify that the new devices are available by expanding your

assigned Symmetrix in the Tree panel. You should see the new devices under the

Standard Devices folder in the Unmapped Devices. Write the device numbers here:

______________________________________________________________________



Part 1B: Create Symmetrix Devices using Symmetrix

Management Console (VMAX)

If you are going to perform this step using Symmetrix Management Console you will first need to complete Part 1 of Lab Exercise 4. If the host that you are launching SMC from is already registered as a ControlCenter Client, you may disregard proceed as normal as Part 1 of Lab Exercise 4 has been completed for you.

Step Action

1 Investigate the Current Environment.

Select Properties from the Tool Bar and then select Storage Systems from the Tree Panel.

Look for the column Unconfigured Capacity in the Target Panel.

Is there Unconfigured Capacity available on the Symmetrix assigned to your lab group (the

Symmetrix attached to your assigned host)? Record the Symmetrix Serial

Number:_____________

Part 4: Map Logical Volume to Array Ports (Pre-VMAX)

The procedure for mapping Symmetrix logical volumes to front-end array ports is different on a Symmetrix VMAX array than on previous Symmetrix arrays (i.e. DMX Models). This lab exercise outlines the procedure for mapping Symmetrix logical volumes to FA ports on Symmetrix models prior to the release of VMAX arrays. You cannot perform this lab

exercise if you are using VMAX arrays and must use Lab Exercise 4, Part 5 to complete both mapping logical volumes to FA ports and allocating the logical volumes to hosts.

Step Action

1 You need to find two array ports to map your Meta device to. For an effective test of both

the Symmetrix configuration and the SAN management exercise to come, the ports:

Should not be the same ports your host is already using—use Path Details to make

sure

Should be connected to the same fabric your host is currently connected to—use

Topology to make sure

Write the names of the ports you chose here:____________________________

2 Select the BCV Meta device you created previously in the tree panel. Make sure that the

Storage Allocation button is pushed down. Then access the icon for SDR operations from

the menu bar.

Acknowledge the information message by clicking the Ok button.

3 From the Select Devices panel of the SDR dialog, highlight the BCV Meta device you

created earlier (you may have to drill down into the unmapped devices folder). In the Select

a Port panel of the SDR window, select one of the host director ports to which you want to

map this device. Then click Move. The device(s) is/are moved from the unmapped folder to

the port that you chose and a Target ID/LUN is automatically assigned. If the automatically

selected Target ID/LUN is not suitable, then click in the Address column to change the

TID/LUN assignment.

4 Now copy your new device mapping to the other port you chose. Select the device in the

Host Directors part of the Select Devices panel. Then select the new array port from the

Select a Port panel, and click Copy. Again, review the TID/LUN.

<Continued>



Step Action

5 Click Continue to move to the review page of the dialog. Review the changes to be made

and click Execute to commit the changes.

Zoning Policy window will pop up.

c) Choose the Zoning Policy you created in Step 1 from the drop down list.

d) Click OK and verify that the Zoning Policy has been set on the Fabric by adding the

Fabric to a Properties view.




Part 2: Import Active Zone Set

Step Action

1 Import Active Zone Set

Expand the Connectivity folder down to Fabrics, and locate the fabric that provides

connectivity between the host and array that you have been assigned. This fabric will be

called Your Fabric throughout this exercise.

2 Import the active zone set to ensure that the definitions being used by the switches are the

ones you are working with in ControlCenter. Right-click your fabric and select Zoning

Import Zone Set Import Active.

3 Choose Continue and Overwrite then Click Execute. Choose a new task list, enter the

name for the new task list and the task. Make sure the View Progress box is checked. Click

OK.

The target panel will show the progress of the task list and the task.

Verify that this task has completed successfully.




Part 3: Create New Zones

Step Action

1 In this part, you will create two new zones to connect your host’s HBAs to the array ports

that you mapped your Symmetrix Meta Device to a few exercises ago. You should have

written those port names down in that exercise.

Use the Properties view to record the names of your host’s HBAs

Host HBAs: _________________________ __________________________

2 Open your fabric and right-click Planned Zones. Select New Zone. The new zone

editor window will pop up.

3 Choose the Zoning Policy you defined in Part 1 from the drop down list. Select one HBA

listed above and click Add, select one of your Array Ports and click Add. Choose OK.

4 Repeat the above to create a zone for the other HBA / Array Port pair.

5 Record the names of your new zones here:

__________________________________________________________________

__________________________________________________________________




Part 4: Edit Copy of Active Zone Set

In this part, all of the students in the class will edit just one planned zone set: the Copy of Active zone

set. This will enable all the changes made by the class to be activated at once when everyone is

finished. In contrast, editing several different zone sets would cause problems, since activating one

would wipe out the changes made by another.

Step Action

1 Add the new Zones to the Copy of Active Zone Set.

Locate the Planned Zone set named the same as the Active Zone Set, but having either Copy

of Active or Modified Copy of Active in parenthesis after the name. It is labeled Copy of

Active when no edits have been made, but as soon as someone in the class performs this

step, it will be labeled Modified Copy of Active.

Right-click the (Modified) Copy of Active Zone Set and choose Edit Zone Set from the

menu. In the dialog, choose the new Zones you created previously from the Available Zones

dialog on the left, and click the Add button to add them to the Zone Set. Click OK to save

this change.

2 Verify that the new Zones appear in the Zone Set by drilling down.

3 Compare Zone Sets.

Right-click the Modified Copy of Active Zone Set and choose Zoning Compare with

Active Zone Set from the menu. The dialog should indicate the changes you, and possibly

some other students, have made to the Planned Zone Set. Close the dialog once you have

verified the change.




Part 5: Activate a New Zone Set

Please coordinate with your instructor before performing this part. It would be best if the Modified

Copy of Active Zone Set were activated just once for the whole class. This ensures that the Last

Active copy of the Zone Set is the original copy.

Step Action

1 Right-click the Planned Modified Copy of Active Zone Set that you edited in the

previous step. Select Zoning Activate Zone Set. In the dialog that appears, verify the

changes to be made as you did in the Compare Zone Sets dialog.

If you are NOT ACTIVATING THE ZONE SET YET, choose CANCEL now.

2 Otherwise, click Execute. Choose a new task list, enter the name for the new task list and

the task, make sure the View Progress box is checked. Click OK.

3 The target panel will show the progress of the task list and the task.

Verify that this task has completed successfully.

VMAX Perform this step only if you have been configuring an array with VMAX features. If

so, you may skip Lab Exercise 6 Part 6.

Once you have activated the zone set and the task has completed successfully, verify that

your zones have been added to your fabric’s Active Zone Set.

Next, verify that the devices you added to your array’s Storage Group have been correctly

masked to your host?

How do you know the device is masked? _______________________________________




Part 6: Symmetrix Storage Device Masking (Pre-VMAX)

Symmetrix device masking with arrays that are not equipped with VMAX features and functionality is performed by modifying masking configurations in the VCMDB. VMAX equipped arrays perform both masking and mapping configurations using Storage Groups

and hence, lack a VCMDB. This lab exercise can only be performed for arrays that are

not equipped with VMAX capabilities.

Step Action

1 Display Current Masking.

Change the target panel to the Masking view by choosing Masking from the Storage

Allocation pull down. Storage Allocation Masking.

2 In the Tree Pane, select your host. Use the controls to show all the devices accessible by this

host.

3 Mask New Devices.

Right-click the host and select Masking Modify Masking Configurations.

4 In the Modify Masking Configurations window, select both of the host ports, the correct

Symmetrix, and both of the storage ports contained in the zones you created earlier.

Note: Only the storage ports that are actually zoned to this host will appear in the Select Storage Port dialog, so

if you did not activate the zone set you created earlier, the ports for your new zone will not appear. To show

all ports, set the Select Storage Array pull-down to SAN Physically Connected and click the array again.

5 Select All Devices from the device pull-down and click Show Devices to display the

devices that can be masked. Choose the Meta device you created earlier, and click the

Grant button.

Finish the action by clicking Continue. Review the changes, make sure the Activate

VCMDB box is checked, and click Execute. Choose a task as you have done before and

make sure you can monitor the results. Continue with the exercise when the task has

completed.



Step Action

6 Clear the Console view, make it a Masking view, and drag your host to it again. Use the

controls to display the devices masked to your host.

Remembering that access-granted devices are in green, can you validate the changes you

have made?

Note: Again, if you did not activate the zone set, you will have to choose the SAN Physically Connected pull-

down of the Select Storage Array part of the dialog.

7 (OPTIONAL) As a final check, perform the host configuration steps discussed in the course

to make the new devices visible to your host. The steps will be different for different

operating systems.

Lab Exercise 9: Alert Planning (Optional)

Purpose:

To work out ControlCenter alerting solutions for common business

needs.


Search the Alert Management area of ControlCenter for specific

alerts

Match available alerts to specific requirements

Propose alerts for use in detecting issues

References: Module 6: Alert Management and Framework Integration




Part 1: File Server Scenario

In this scenario, you will propose ControlCenter alerts for a file server environment. This is a written

exercise—you are not required to implement the solution. However, you should be using the Console

to investigate the alerts when developing your solution.

This scenario is optional: complete it if you have enough time.

Scenario: The maintainers of a file server have asked you to propose the best ControlCenter alerts for

monitoring their task. The server is a Solaris host that maintains several critical user shares. All of

the shares are built from the same large Veritas volume group. Some unallocated space is available in

the volume group for future expansion of the file systems. The files in the shares are typically small

user documents and are constantly being added and removed.

The primary concern is the free space on the file systems and volume group. They would like to be

warned if any file system is more than 80% full, or if there is less than 100MB of unallocated space in

the volume group.

Additionally, their server has recently been required to host additional software that is interfering with

their operations. Conflicts with this software have caused the nfsd process to repeatedly fail, and the

CPU utilization to sometimes spike over 90%. They would like to be warned of these events as well.

The CPU spike is brief enough to be considered a low severity issue.

What ControlCenter alerts would you recommend for this group? Record the names of the alerts and

what agent they apply to below. Also be sure to note any changes to the defaults in the Source,

Conditions, Actions, or Apply To tabs.




Part 2: Database and Backup Scenario

In this scenario, you will propose ControlCenter alerts for an environment containing several

databases and a backup application. This is a written exercise—you are not required to implement

the solution. However, you should be using the Console to investigate the alerts when developing

your solution.


Scenario: A group responsible for the upkeep of several database applications would like you to find

the best ControlCenter alerts to set for their situation. Their environment contains two Oracle

databases hosted on two Solaris hosts and one SQL Server database hosted on a Windows host. All

of these applications are backed up by Legato Networker, which is running on a separate Windows

host.

The group would like to be notified as soon as a database application goes down. There should be at

most a 2 minute delay between the time the database goes down and the alert arrival. Additionally,

any available alerts on data size or table space usage should be enabled to warn when there is less

than 10% free space.

Since the databases are not growing quickly in size, the backup solution uses a fixed, predictable

number of tapes. Therefore, any significant change in the data size (more than 20% increase) should

be reported, if possible. Additionally, the group would like to receive notification of any Networker

product errors or warnings through the ControlCenter alerting system. If this can be done, match the

Networker warning levels to the appropriate ControlCenter alert severities.







Part 3: SAN and Storage Performance Scenario

In this scenario, you will propose ControlCenter alerts for notification of performance issues. This is

a written exercise—you are not required to implement the solution. However, you should be using

the Console to investigate the alerts when developing your solution.


Scenario: A local performance guru has analyzed this group’s environment and identified thresholds

that will cause response time problems if exceeded. The group would like to be alerted when the

performance parameters exceed the thresholds. Take care not to issue performance alerts for spike

events—the alert should only be generated if the threshold has been exceeded for a minimum of 10

minutes at a time. The group understands that the polling process used by the agents can only

approximately be used to identify an event that lasts for a full 10 minutes, but please use whatever

ControlCenter features are available to reach this goal.

The fabric switch ports are the first concern. The performance guru suggests that an issue should be

reported if any port processes more than 3000 frames per second for 10 or more minutes.

Additionally, an alert of the highest severity should be issued if any port fails.

The Symmetrix FA ports are also a concern. If the I/O per second measure exceeds 1500 for 10 or

more minutes, an alert should be triggered. Additionally, system-wide Symmetrix performance

measures should also trigger alerts as follows:

Hit % - alert when below 50%

I/O per second – alert when above 10000

Throughput – alert when above 60000 KB/sec






Lab Exercise 10: StorageScope Reporting

Purpose:

17 Feel free to look around at the rest of the Switches views to familiarize yourself with the

features.




Part 2: Using the Dashboard

Step Action

1 If you are not already logged in to StorageScope, log in now. Since the Dashboard is the

start page of the interface, you may go to the next step.

If you are already logged in to StorageScope, click the Dashboard menu to go to the

Dashboard page.

2 Use the Customize link at the top to add a few snapshots to the display. Choose the ones

you are most interested in so you can see what they display. If they are all currently

displayed when you open the dialog, remove a few instead.

When you save your changes and return to the Dashboard, the added snapshots will

probably contain the phrase: building snapshot. In a few seconds it will automatically

refresh, showing the results.

Tip: If you see unexpected changes to the Dashboard, remember that some of your

classmates are using the same StorageScope FLR Archiver.

3 Now build your own snapshot. Use the Utilities Snapshots menu to get to the Snapshots

page, and click the Custom Snapshots tab.

Click the Create button to launch the snapshot dialog.

Choose Table for the Type.

Choose Storage Arrays for the Category.

Give your snapshot a Title that will differentiate it from the ones the other students create,

but include Array Capacity somewhere in the title.

Use this code for the SQL Query:

select unique a.ArrayAlias, m.ArrayRawTotal

from SRMArray a, SRMArrayMetrics m

where a.ArrayKey = m.ArrayKey

Preview your snapshot to make sure there are no typos.



Step Action

4 Now change the snapshot to one of the chart types. A bar chart will work well for this data.

Preview the results to make sure it displays the information.

Save the snapshot when you are satisfied with the results.

5 Return to the Dashboard page, and add your new snapshot to the display.




Part 3: Launching and Filtering Interactive Reports

Step Action

1 Log in to the StorageScope interface if you are not already logged in.

2 Select Analysis Reports Built-In/Custom Reports from the menus. This page holds

all of the built-in an user-defined reports.

3 Choose the Arrays report radio button, and click the Run Report button.

Take the defaults at the filters dialog, except for the Name. Use a unique name that will

differentiate your output from the other student’s reports.

Then click Run Now to execute the report.

4 The interface will automatically switch to the Interactive Reports page, where you can

monitor the progress of your report. The page will automatically refresh when the report

status becomes Completed. Click the report name to launch the results.

Are storage allocation details presented for each array in your environment? ____

What levels of summary are available?

5 Return to the Built-In/Custom Reports page, and launch the Arrays report again. This

time filter it as follows:

Name (of report): Use a unique name.

Array Type: Choose just one of the types by clicking on it.

Wait for the report to complete at the Interactive Reports page as before.

Does the report contain information for just one type? ___________________



Step Action

6 Return to the Built-In/Custom Reports page, and launch the File Type Usage Trending

report. Filter it as follows:

Name: Use a unique name.

Output Format: Choose a different, readable format like RTF, HTML, or XLS.

Host Names: Choose just two hosts by control-clicking.

File Types: Choose just Executable files and Temporary files.

Trending Type: Choose Daily.

# Trending Data Points: Choose 7.

Wait for the report to complete, and verify that the output matches the filters you chose.

Tip: Your environment might not actually have seven days of daily trending data.

7 Create a Chargeback report for a few folders in your environment. You will have to start by

creating a File Group for Chargeback. Launch the appropriate page under the Utilities

Settings menu.

Use the Create button at the bottom of the page to create a new file group.

Choose a unique Name and Chargeback value for file group.

When the page for your new file group appears, use the Add button to add two or more file

systems or folders. The Browse button of the Add dialog is the most convenient way to

ensure that the names you choose match existing folders.

8 Return to the Built-In / Custom Reports page, and launch the Chargeback report. Filter

the report so that it only shows your file group.

View the report output, and verify that it has determined a cost amount for your group.

9 Launch a few more reports. Choose reports that you are most interested in so you can see

what they display.




Part 4: Report Jobs

Step Action


2 Select Analysis Reports Scheduled Report Jobs from the menus. You can edit

automated report jobs on this page.

3 Create a new report job with the following settings:

Name: Use a unique name.

Output Type: File.

Output Format: Any format that you can easily read will do.

Output Path: Important! Do not keep the default path. Create a unique path name by

typing a slash and a unique name after the Exports part of the path.

Save your configuration as a new report job.

Tip: Did you try the Browse button when creating a new Output Path? This feature

only lets you choose existing folders. To create a new one, type the new path name

right in the Output Path box.

4 The interface should automatically switch to the page for your new report job. Use Add

button in the Reports & Report Groups tab to add these two reports:

Hosts

Databases

Add one or two other reports that you are interested in as well (if several students are

sharing the same FLR Archiver, adding more than a few will slow your work down).

5 Use the Change button in the Schedule tab to schedule the report to run sometime after the

default Extraction, Translation, and Load process at 04:00 am.



Step Action

6 Click the Start button in the Status tab to run your report job now.

Unlike some of the other displays, this one will not automatically refresh to show you the

progress. Use the Refresh button in the Status tab to update the display until you see a

completed successfully event in the Status tab.

How long did your job take to run? ________ (The Status tab has this information)

7 Go to the Analysis Reports Report Job Results page, and click each of the reports to

view the results.

Can you be sure that these reports are from your report job and not another student’s job?

Since the Report Job Results page only shows the last copy of a report, and other students

may be using this FLR Archiver host, you cannot be sure that the outputs are from your job.

8 Since you created a unique output folder to hold your reports, you can be sure that they exist

on the FLR Archiver host, even if the Report Job Results page may not link to them. You

will have to access the files directly.

You will need to know what file system on the FLR Archiver host your reports are stored in.

Do you remember? You can click the Settings button on your report job’s page to review

the file system and path you chose for the output. In most lab environments, it is the E:

drive, but check to be sure.

You will also need to know the network name of the FLR Archiver host. It is displayed in

the URL of the StorageScope interface.

9 Go to the Windows desktop of your host and open a share to the file system on the FLR

Archiver that stores your reports. One way to do this is to click the Windows Start Run

menu, and enter the UNC of the administrative file system share. It will look like:

\\FLR Archiver\C$

Substitute FLR Archiver with the actual network name of your FLR Archiver, and use the

correct file system name in place of C. Do not forget the trailing $, and do not use a colon.

If it prompts for authentication, use Administrator for the login and student as the password.

If it is successful, a window displaying the remote file system should appear.



Step Action

10 Follow the path you chose for your report output to locate your files. Double-click them to

view the results.

Now you can be sure that the results are from your report job.

Tip: Do not close this share window! You will need to view your report job outputs

again later in this part.

11 Return to your report job (under Analysis Reports Scheduled Report Jobs your

report job name), and set an Aggregate filter to apply to your reports. Click the Change

button in the Aggregate Filters tab of the report job.

Leave all the filters alone except for Host OS. Select just one or two (but not all) of the

operating systems by control-clicking them. Save your aggregate filters.

12 Use the Start button in the Status tab to manually run the report job again. Refresh the

page to detect when the job is complete as you did before.

When the job is complete, use the share window—not the StorageScope interface—to view

the results. Answer these questions:

Did the filter restrict the output of the Hosts report? _______

Did the filter restrict the output of the Databases report? _______________



Lab Exercise 10: StorageScope Queries

Part 5: Using Queries

In this part, you launch some StorageScope queries and make a few minor modifications.

Query Reporting Needs


2 Select Analysis Queries Query Builder from the menus. This page holds all of the

built-in and user-defined queries.

3 Run a query that you know will have some output, such as Array Utilization Details, Fibre

Channel Switches, or Host and Array Devices. Do this by selecting the radio button next

to the query, and then clicking the Run button at the bottom of the page.

View the output, and also the SQL code that generated the query.

4 Use other built-in queries to find this information.

Tip: If the name of the query is a blue hyperlink, then some other student has already

created an output. You can just click the link to view the results.

List all allocated array devices, their sizes, and the array ports allocated through.

Query used? _________________________________________________

List host devices, their connection to arrays (if applicable), and their capacities.

Query used? _________________________________________________

List each host, its name, a summary of the number of LUNs allocated to it, their total

capacity, and the total raw capacity.

Query used? _________________________________________________

List the characteristics of all of the Fibre Channel HBAs discovered.

Query used? _________________________________________________

List array names, their microcode version, and cache sizes.

Query used? _________________________________________________




5 As a way of exploring the query tool interface, let us make a few small changes to an

existing query. Built-in queries cannot be edited, but you can make changes to a copy of a

built-in query.

Select the Array Utilization Details radio button, and then click the Copy button at the

bottom of the page.

6 In the Define Initial Settings page of the dialog, just change the Name of the query to

something that will distinguish it from the other students’ queries.

Click Next to get to the next dialog page.

7 In the Select one to eight related Areas of Interest page, do not make changes.


8 In the Select Columns page:

Add the Arrays.Unconfigured column to the display

Remove the Arrays.FS on Array column from the display


9 In the Create Filters page, add this filter:

Column name: Arrays.Unconfigured

Operator: >

Value: 1000000 KB

Can you substitute another unit for ―KB‖ in the Value column of the Filters Dialog?

_________________________________________________________________________

Tip: All of the arrays will probably meet this condition. Once you see the values this

query produces, you can return to this page and adjust the filter so only the arrays with the

most unconfigured capacity appear in the output.


10 In the Select sorting, grouping & total options page, do not make changes.





11 In the Select Run Settings page, change the output to any one of the File formats. This

will preserve the results until they are overwritten.

Choose the units in the Select Unit dialog box to show how the array measures will be

displayed in the columns at the end of the query.

Use the Save button to save your query.

Use the Run Now button to run the query. When it is complete, click the indicated link to

view the results.

12 Try another type of output too, just to see what they look like.

Return to the Queries page, select your query, and click the Modify button.

Tip: Can’t see the query you just saved? Use the browser to refresh the Query page.

Use the Next button to go through all of the pages until the Select Run Settings page.

There, change the file format to one of the others—choose CSV if you originally chose

PDF, for example.

Save and Run the query again to view the output.




Part 6: Create a Query

In this part, you create a StorageScope query that shows the file systems on hosts that are stored on

array devices.

Step Action


2 Select Analysis Queries Query Builder from the menus. This page holds all of the

built-in an user-defined queries.

3 Use the Create button to create a new query.

4 In the Define Initial Settings page:

Choose a Name that will uniquely identify your query.

Choose an appropriate Description and Query Category also. Use these features to

tell other users that the query shows array-based file systems.

Choose the Current Data for the time period.


5 In the Select one to eight related Areas of Interest page:

Before choosing the actual areas of interest (tables) for this query, let us experiment with

this interface for a moment. Find out which of these combinations of areas is legal in a

query—an error message will appear at the top if it is not:

Hosts and Arrays. Error? ______

Hosts, Switches, and Arrays. Error? ______

Hosts, Host Devices, and Arrays. Error? ______

Arrays, NAS Servers. Error? ______

Arrays, Storage Devices (under NAS), NAS Servers. Error? ______

You see that you frequently have to choose one or more link tables to connect the ones you

want. Try this experiment: you would like to include both the Databases and Arrays tables

in a query. What other tables are needed to avoid an error in this dialog?



Step Action

6 Still in the Select one to eight related Areas of Interest page:

Now select the areas of interest for this query: Hosts and File Systems.


7 In the Select Columns page:

Choose these columns for your query:

File Systems.File System

File Systems.File System Name

File Systems.File System Type

File Systems.Free File System

Hosts.Host Name

Hosts.Host OS Type

Feel free to reorder them any way you like.


8 In the Create Filters page, you will filter the query so that only file systems residing on

arrays are displayed.

In the first filter, choose these settings:

Column name: File Systems.Resides on

Operator: equals to ignore case

Value: Array




Step Action

9 In the Select sorting, grouping & total options page, you will sort the output on the host

name column, and then on the file system name.

In the first sorting row, choose these settings:

Column name: Hosts.Host Name

Sort type: Ascending

Subtotal by: selected

In the second sorting row, choose these settings:

Column name: File Systems.File System Name

Sort type: Ascending

Subtotal by: not selected


10 In the Select Run Settings page:

Keep the defaults that limit the maximum number of records and the maximum run time.

Choose the File output type, and any format you would like.

Select the Units for the values that will be displayed in the queries.

Use the Save button to save your query.

Use the Run Now button to run the query. When it is complete, click the link as indicated

to view the results.

Tip: If the query returned no results, edit it to remove the filters (the goal of the next

step). If there are still no results, use the SRM Views to make sure some file systems

were recorded in the last ETL.

11 Return to the Queries page, select your query, and click the Modify button.

Tip: Can’t see the query you just saved? Use the browser to refresh the Query page.

Do not make any changes until you reach the Create Filters page again. There, remove the

filters so that the query shows all file systems.

At the Select Run Settings page, click the View SQL button to look at the code for this

query. I’m sure you are happy you didn’t have to write that by hand!

Save the query, and run it now to see the change you made to the filter.




Part 7: Create Scheduled Query Jobs

In this part of the lab exercise, you will create Scheduled Query Jobs using built-in queries and the

queries you have already created.

Step Action


2 Navigate up to the Analysis menu and select Queries Scheduled Query Jobs

Note You may notice that the Scheduled Query Jobs menu looks very similar to the Scheduled

Report Jobs menu, yet with a few more options.

3 Create a new job by clicking on the New button

In the 1. Set Job Details tab, give the query job a unique name so that you may identify it

from other students scheduled jobs.

Change the Start Time to 15 minutes past the current time. Is the default start time before

or after ETL? Why?

_________________________________________________________________________

Keep the default values for both Start Date and End Date.

4 Click on the 2. Choose Queries tab. Find the queries that you have both modified and

created in previous parts of the lab exercise and add them to the job. You may also add any

other queries you find interesting, but make sure there is at least two queries.

Click on the Filter By Category pull-down menu. Are these the same categories that are

listed in the Details page of the Query Builder? __________________________________

When you have selected all the queries

5 Select the 3. Select Recurrence tab and keep the default Daily setting.

Even though you should keep the Daily setting, click on the Weekly and Monthly settings

and see how the options for each change. Make sure that you select Daily before moving on

to the next step.



Step Action

6 Finally, select 4. Set Output Format tab.

Choose the Output Type and Output Format to the type and format you would like to

see. Is there an option to export to HTML or the Screen? ___________________________

Where might the output formats be saved to? ____________________________________

Save the query job once you have selected the outputs. This should bring you back to the

Scheduled Query Job homepage.

Does your scheduled query job appear in the Scheduled Query Jobs homepage with any

other students? ____________________________________________________________

Is the Start Time you specified in the query job listed in the Next Start Time

column?__________________________________________________________________

Option: You may choose to run the query job by selecting the Run Now button or you can

wait for the specified Start Time to view the query outputs.

7 Once the query job has successfully completed, the names of the queries should appear as

Blue Links under the Query Names column.

Click on the query names to open the queries individually and view the output.

Lab Exercise 12: Task Lab – Provisioning Storage to a

Server

Purpose:

To work out a complete storage provisioning solution including

investigation of the current environment, planning the solution,

executing the solution with the approval of a Change Control Board, and

finally enabling monitoring for the result.


Investigate current storage configuration and plan for new storage

allocation needs

Allocate new storage

Set alerts for the new storage

References: Module 9: Storage Allocation Scenarios



Lab Exercise 12: Task Lab – Provisioning Storage to a Server

Part 1: Plan for New Storage

In this exercise, you will plan for new storage for your Server, and investigate the current

environment.

Requirements

A new application is being set up on your Server , and you must provision new storage for the task

(your instructor will tell you which of the hosts assigned to your group will be used to simulate the

Server) The storage must:

Appear as one device (LUN) to the host

Be a minimum of 3 GB in size

Use array-based RAID-1/0 protection (mirroring and striping) – Must use 8 array devices

Be accessed by the host over redundant paths, if possible (only if multiple fabric connections

to the array are/can be made)

Investigate and Plan

Investigate the current environment to determine how much of the required configuration already

exists. Use ControlCenter Views to fill out as much of the information on the Task Lab Worksheet

(at the end of this lab) as you can. The gaps in this worksheet will have to be filled in by changing the

configuration. For example, if the needed storage does not exist, it will have to be created. If the

necessary zones linking the host to the array do not exist, they will have to be created.

Plan the necessary changes for the new storage allocation. You should meet the requirements using

the minimum number of configuration changes. Using a minimum of configuration changes, a task

can be finished faster and uses existing resources before demanding new ones. Do not use storage

devices that are already in use, however. Devices that are allocated to a file system, database, volume

group, or another host are considered in use.

As an example investigation method, consider investigating the answers to the following allocation

questions:

Is there an unused device meeting the requirements already allocated to my host?

If not, is there an unused device already mapped to the correct array port[s]?

If not, is there a device configured on the array not mapped to any ports?

If not, can such a device be created from pre-configured storage (devices, RAID groups)?

If not, is there sufficient unconfigured storage on the array to create the device?

Continue using the Task Lab Worksheet to plan your needed configuration changes. Write the

proposed changes on the worksheet, making sure to check the Change Required column.




Part 2: Provision New Storage

In this exercise, you will make the necessary configuration changes to provision the new storage.

Warning: To avoid conflicts, the class Change Control Board will approve and execute all array

configuration changes. NO array changes are to be made without following the proper change

control procedure set up by the instructor.

Submit Your Request to the Change Control Board

Your Task Lab Worksheet should now show existing configuration features and changes that must

be made to the configuration to allocate your storage. Submit your desired changes to the Change

Control Board. The CCB will perform a basic validation check and schedule the changes to be

executed. A check will also be made to ensure that conflicts over shared resources do not arise.

Changes for several groups might be performed all at the same time to speed the process.

Execute Changes

Once approved, you (or the CCB) will execute the changes. Depending on the number of steps

involved and the amount of shared resources, this phase might take a long time.

After each configuration change, be sure to use Console views to verify that the change has worked.

Scan Host Ports

If the host can identify the new storage, your task is considered complete—there is no reason to

actually build a file system for this lab. A new scan of the host storage ports can be performed right

from the Console. Right-click the Network File Server, and choose Host Rescan Disks from the

menu. Once the host agent re-scans the port[s], the new host device[s] will appear associated with the

host in the Tree Panel (more than one host device will appear if multiple paths were used to present

the storage).

If this step does not work but all of the ControlCenter changes seem to be in place, some

configuration change might be needed on the host itself. Ask your instructor how to proceed.




Part 3: Monitoring and Alerting

In this exercise, you will monitor your new storage and set relevant alerts.

ControlCenter Console Monitoring

To verify that the ControlCenter agents have observed the changes that you have made, log in to a

Console and show a Relationship View of your file system. Verify that the device names and device

configuration displayed in the view matches your expectations.

Also show a Topology View that includes all of the hardware used to store and present the storage to

your Network File Server host. Drill down into the Active Zones area of the Tree Panel and highlight

the zone used to make the device available to the host. Verify that everything meets your

expectations.

ControlCenter Alerting

Ensure that the following conditions trigger alerts for your group. Use management policies to

deliver the alert only to users concerned with the issue. For resources owned exclusively by your

group, the alert should go only to your group’s users. For shared resources, add your group’s users to

the management policy without removing other group’s users.

In each case, write the name of the alert that covers that condition. If no such alert exists in

ControlCenter, write n/a.

Trigger a low severity alert when the new file system becomes 70% utilized, and triggers more severe

alerts at 80% and 90% (although you have not created a file system, you can still set the alert).

Alert: ________________________________________________________________________

Trigger an alert when the Host Agent running on the Network File Server fails.

Alert: ________________________________________________________________________

Purpose:

To work out a complete local replication solution including investigation

of the current environment, planning the solution, executing the solution

with the approval of a Change Control Board, and finally enabling

monitoring for the result.


Plan for a replication solution

Allocate new storage to a host

Use Replicas to copy data




Lab Exercise 13: Task Lab – Local Replica Backup Solution

Part 1: Plan for Replica Backup Solution

In this exercise, you will plan for a local replica backup solution. Storage presented to the production

Server in the previous exercises will be backed up by the Backup Server host.

Requirements

The Backup Server host should be enabled to perform a backup of the file system storage maintained

by the production Server. The solution must:

Use local array-based replication to make a point in time copy of the file system on the

Network File Server host

Present the copy to the Backup Server host over a minimum of one pathway

Note: the file system on the production Server host should have been completed in a different lab. If

it does not exist, consult with your instructor to determine what should be used as the source of the

backup.

Investigate and Plan

Investigate the current environment to determine how much of the required configuration already

exists. Use ControlCenter Views to fill out as much of the information on the Task Lab Worksheet

(at the end of this lab) as you can. The gaps in this worksheet will have to be filled in by changing the

configuration. For example, if the needed storage does not exist, it will have to be created. If the

necessary zones linking the host to the array do not exist, they will have to be created.

Plan the necessary changes for the new storage allocation. You should meet the requirements using

the minimum number of configuration changes. Using a minimum of configuration changes, a task

can be finished faster and uses existing resources before demanding new ones. Do not use storage

devices that are already in use, however. Devices that are allocated to a file system, database, volume

group, or another host are considered in use.

Arrays often have more than one way of setting up local replication. Use any method that presents a

complete point in time copy of the source data to the Backup Server host. Make sure you are

completely familiar with the operation of the replication method you are using, and how EMC

software is used to perform the task. If you are not sure, consult with your instructor.




Part 2: Create Replica

In this exercise, you will use the replication software to copy the source data from the Network File

Server to the Backup Server.

Warning: To avoid conflicts, the class Change Control Board will approve and execute all array

configuration changes. NO array changes are to be made without following the proper change

control procedure set up by the instructor.

Submit Your Request to the Change Control Board

Your Task Lab Worksheet may now show existing configuration features and changes that must be

made to the configuration to allow the local replication. Submit your desired changes to the Change

Control Board. The CCB will perform a basic validation check and schedule the changes to be

executed. A check will also be made to ensure that conflicts over shared resources do not arise.

Changes for several groups might be performed all at the same time to speed the process.

If no configuration changes are needed, proceed to Create Replica Copy.

Execute Changes

Once approved, you (or the CCB) will execute the changes. Depending on the number of steps

involved and the amount of shared resources, this phase might take a long time.

After each configuration change, be sure to use Console views to verify that the change has worked.

Create Replica Copy

Use the appropriate software to make the replica copy of the source. The copy is considered complete

when all of the data can be presented to the Backup Server host.

Scan Host Ports

The backup host must be able to identify the copy as a new device. A new scan of the host storage

ports can be performed right from the Console. Right-click the Backup Server, and choose Host

Rescan Disks from the menu. Once the host agent re-scans the port[s], the new host device[s] will

appear associated with the host in the Tree Panel (more than one host device will appear if multiple

paths were used to present the storage).

If this step does not work but all of the ControlCenter changes seem to be in place, some

configuration change might be needed on the host itself. Ask your instructor how to proceed.




Part 3: Monitoring and Alerting

In this exercise, you will monitor your results and set relevant alerts.

ControlCenter Console Monitoring

Check the Topology View and Relationship View to verify the configuration of replica storage.

ControlCenter Alerting

Ensure that the following conditions trigger alerts for your group. Use management policies to

deliver the alert only to users concerned with the issue. For resources owned exclusively by your

group, the alert should go only to your group’s users. For shared resources, add your group’s users to

the management policy without removing other group’s users.

In each case, write the name of the alert that covers that condition. If no such alert exists in

ControlCenter, write n/a.

Trigger an alert when the Host Agent running on the Backup Server fails.

Alert: ________________________________________________________________________

Alert when the array directors used by the Backup Server experience a fault.

Alert: ________________________________________________________________________

Alert when any of the switch ports used by the Backup Server change status.

Alert: ________________________________________________________________________

Assume that the Legato Networker product will be used on the Backup Server to perform the

backups. Enable the alerts that you would you set to monitor the status of the backups, and write the

names of the alerts below:

Alert[s]:

______________________________________________________________________

Lab Exercise 14: Task Lab – Reporting Scenarios

(Optional)

Purpose:

To work out several realistic reporting solutions.


Use ControlCenter StorageScope reports in reporting scenarios

Locate configuration, allocation, and utilization information




Lab Exercise 14: Task Lab – Reporting Scenarios (Optional)

Part 1: Reporting

Several physical and logical asset report tasks will be presented in this exercise. Use the

ControlCenter Console, StorageScope, and possibly other reporting and presentation tools (Microsoft

Word, Excel) to generate your reports. Use as many actual reports as you think are necessary to fully

present each issue to the target audience.

No configuration changes are required for this exercise.

Report: Specific Storage Allocation Request

Audience: Budget Managers, IT Managers, IT Change Control Authorization

You have been asked to show the feasibility of a request for an additional 70GB of storage which will

be added to one of the servers in your group (pick one). The data to be stored on the new allocation

does not require high levels of performance, and can be presented in any number of devices. It is

expected that the application will require some additional increase at a later time.

Several other authorities will need to approve of this request, and they will need a detailed report

showing that sufficient free storage is available, and a proposal on how it will be configured. Your

report should also include estimates on how soon the storage will be depleted if a request like this

occurs every month.

Remember that your group shares array space with the other classroom groups, and that they all are

receiving identical requests for new storage allocation.

Report: Unused Storage

Audience: IT Managers, Systems Administrators

You have been asked to generate a report summarizing the unused storage in your environment as

part of your monthly reports. Categorize the results by the type of unused storage:

Storage in host accessible devices not used in a file system or database

Unused storage space in file systems or databases

Use enough detail to help locate the host or array with the most unused space, but don’t actually list

every device or file system in the environment.

Report: Chargeback

Audience: Budget Managers

Create a chargeback report that shows the total cost of files used by each group. Include any non-

system file system on any of the group’s hosts. System file systems (C: and /) should be omitted from

the report. The charge to each group will be $0.35 per gigabyte.

This report will have to be generated each month as part of the internal billing cycle.



Lab Exercise 15: Storage Provisioning Services

Purpose:

To use Storage Provisioning Services to automate storage allocation

tasks.

Lab Exercise 15 can only be used with pre-VMAX arrays. VMAX

arrays do not support the features and functionality of Storage

Provisioning Services.


Create and populate Storage Pools.

Define Storage Policies.

Create Storage Allocation Tasks.

Execute Storage Allocating Tasks.

11 Click Save to save the policy.

12 Verify that mypolicy appears under Allocation Policies folder.




Part 3: Storage Allocation Task

Step Action

1 In the tree pane, expand the Hosts folder and right-click the host assigned to you.

2 Select Allocation Allocate.

3 In the Storage Provisioning Services Wizard, verify that mypolicy has been selected. If

not, select mypolicy from the drop-down menu.

4 Select More Options.

5 Specify At Most xx GB. Ask your instructor for the amount of storage to be allocated.

Click Next

6 Verify the details of proposed path. Change any fields if necessary. Click Next.

7 Review Specification and Path Details. Click Execute Later.

8 Specify mytasklist for the Task List Name and mytask for the task name, replacing my with

your initials.

9 Verify that mytask has been placed under mytasklist in the Allocation Task Lists sub-folder

of the Task List folder, in the tree pane.

10 Prior to executing the task list, consult your instructor. You can execute the task list by

right-clicking on the task list and choosing Execute Task List.
