1. Installing EMC PowerPath:

Change the directory to the directory where EMC PowerPath tar file resides.

Unzip the package

#gunzip EMCPower.SOLARIS.5.2.SP2.b012.tar.gz

Untar the package

#tar -xvf EMCPower.SOLARIS.5.2.SP2.b012.tar

Run package add command to install the package-

#pkgadd -d EMCPower.SOLARIS.5.2.SP2.b012

The following packages are available:

1 EMCpower EMC PowerPath

(sparc) 5.0.x_bxxx

Select package(s) you wish to process (or 'all' to

process all packages). (default: all) [?,??,q]:

Enter 1 and press ENTER.

You are prompted for the directory where the PowerPath

program files will be installed:

Enter package base directory (default: /opt):

Press ENTER to accept the default base directory (/opt), or type the

path to an alternate base directory and press ENTER.

This package contains scripts which will be executed

with super-user permission during the process of

installing this package.

Do you want to continue with the installation of

[y,n,?]

Enter y and press ENTER.

Once the installation is complete register the powerpath.PowerPath takes the older registration key if there are

any previously registered powerpath on the host.

1.1 Registering PowerPath:

1. Enter:

#/etc/emcpreg -install

============ EMC PowerPath Registration =============

Do you have a new registration key or keys to enter? [n]

2. Type y and press ENTER.

You see the following output:

Enter the registration key(s) for your product(s),

one per line, pressing Enter after each key.

After typing all keys, press Enter again.

Key (Enter if done):

3. Enter the PowerPath registration key and press ENTER. If you entered a valid key, you see the following output:

1 key(s) successfully added.

Key successfully installed.

Key (Enter if done):

4. Press ENTER. You see the following output:

1 key(s) successfully registered.

5. If you are registering PowerPath on a Solaris 10 host, then perform these steps. Otherwise, proceed to the next

section.

a. Run the powermt set policy command to reset the load balancing and failover policy.

b. Run powermt save to save the settings in the powermt.custom file.

6. If you are installing PowerPath for the first time and are prompted to reboot, you must reboot now.

To reboot the host, enter: #reboot -- -r

If the sd or ssd driver does not exist on the host, you see one of the following messages during boot:

WARNING: forceload of drv/sd failed

or

WARNING: forceload of drv/ssd failed

You can safely ignore this warning.

1.2 Verify the PowerPath installation:

Run the following command,

root@hostname01$ pkginfo -l EMCpower

1.4 Verify that PowerPath devices are configured on the

host:

To verify that PowerPath devices are configured on the host:

1. Enter: powermt display dev=all

You should see output similar to the following:

Pseudo name=emcpower0a

Symmetrix ID=000000001400

Logical device ID=048

state=alive; policy=SymmOpt; priority=0; queued-IOs=0

====================================================================

------------ Hosts ----------- - Sys - -I/O Paths - --- Stats -

### HW Path I/0 Path Interf. Mode State Q-IOs Errors

====================================================================

2300 sbus@f/QLGC,isp@2 c2t1d0 SA 16aB active alive 0 0

2301 sbus@f/QLGC,isp@2 c1t1d0 SA 16aA active alive 0 0

2302 sbus@f/QLGC,isp@2 c3t1d0 SA 16bB active alive 0 0

(Output truncated)

2. If the output of powermt display dev=all indicates that some storage system logical devices are not configured as

PowerPath devices:

a. Configure any missing logical devices. Enter:

powercf -q

powermt config

b. Rerun powermt display dev=all to confirm that:

These logical devices are configured as emcpower devices.

The correct failover and load balancing po licy is set.

c. If the failover and load balancing policy is not set correctly, run the command powermt set policy, setting the policy that

applies to your storage systems.

2. Removing PowerPath:

To remove PowerPath from a Solaris host:

1. Log in as root.

2. Start the uninstall program. Enter:

/usr/sbin/pkgrm EMCpower

The following package is currently installed:

EMCpower EMC PowerPath

(sparc) 5.2.x_bxxx

Do you want to remove this package? [y,n,?,q]

3. Enter y and press ENTER to remove the package.

The screen displays the following information:

## Removing installed package instance

This package contains scripts which will be executed with super-user permission during the process of removing

this package.

Do you want to continue with the removal of this package

[y,n,?,q]

4. Enter y and press ENTER to continue with deinstallation. The screen displays information about the removal

process, ending with:

----------------------------------------------------------------* EMCpower successfully removed.

* REBOOT the host to complete the remaining step of the removal.

*

* This reboot may be deferred if you are about to install a

* newer PowerPath product.

*----------------------------------------------------------------

## Updating system information.

Removal of was successful.

2.1 Removing PowerPath files:




4/13

p y y g p p p

The removal process saves the following files, adding the extension .500.saved:

/kernel/drv/emcp.conf

/kernel/drv/emcpsf.conf

/etc/powermt.custom

/etc/emcp_registration

/etc/emcp_devicesDB.dat

/etc/emcp_devicesDB.idx

If the removal program detects existing files with the .4x.saved extension on the host, it overwrites these files.

It does not overwrite saved files that have a different format, for example,

powermt.custom.saved.

If you are removing PowerPath from the host entirely (that is, you are not

planning to re-install PowerPath), remove these files from the host:

1. Enter the following command:

/etc/emcp_cleanup

Note: This command removes the PowerPath license and all supporting

files.

emcp_cleanup issues the following warning:

Warning: Attempt to remove saved configuration files for PowerPath versions. Removing these files will result

in loss of saved configuration and upgrade features.

Proceed with caution!!

Do you want to continue [y,n,?] (default: n):

2. Enter y and press ENTER.

The uninstall program asks for confirmation:

Are you sure [y,n,?] (default: n):

After you remove PowerPath 73Removing PowerPath

3. Enter y and press ENTER.

4. After running emcp_cleanup and verifying no files remain, manually delete emcp_cleanup.

5. No need to reboot the host after the uninstall, if you are planning to install the powerpath

software again. If you are not installing powerpath software then reboot the server.
