7/22/2019 Parameters to Be Added Prior to the EMC Powerpath Installation in Solaris

1/4

Parameters to be added prior to the EMC

powerpath installation in solaris

1.install the latest QLogic driver

2.The /etc/system file must have the following entries:

set lwp_default_stksize=0x6000

set ssd:ssd_max_throttle=20

set ssd:ssd_io_time=0x3c

set fcp:fcp_offline_delay=20

set fcp:ssfcp_enable_auto_configuration=1

3.If the host agent is running on the server, stop it:

/etc/init.d/agent stop

4.Uncomment the following line in the /kernel/drv/iscsi.conf file:

mpxio-disable="yes"

? In addition, if the following line appears in the iscsi.conf file:

mpxio-disable="no"

5.To install PowerPath from a downloaded tar file, for example, after

downloading the package from Powerlink, use this procedure:

1. Select or create a directory where you can unload the PowerPath

tar file. For example, type:

mkdir /unload

2. Change directories to the unload directory.

Note: Ensure that the unload directory is empty.For example, type cd /unload

3. Copy the tar file to the unload directory. Type:

cp /

4.pkgadd -d .

6.You see one of the following prompts:

On SPARC hosts:

The following packages are available:

1 EMCpower EMC PowerPath

(sparc) 5.3.x_bxxx

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

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

You are prompted for the directory where the PowerPath

program files will be installed:

Note: PowerPath installs its files in /basedir/EMCpower; the installation

process creates the EMCpower subdirectory. Make a note of the name

and location of the PowerPath base directory for future reference.

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.

7. You will see the following prompt:

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,?]

Type y and press Enter.

8. The screen displays information about the installation ending

with:

-------------------------------------------------------

* EMCpower Installation:

*

* Installation is successful.

*

* Please REBOOT the host to complete the remaining steps

* of the installation. Refer to the PowerPath for Solaris

Installation and Administration Guide for more

* information.

*

* If you have a license key card, register now.

*

* License registration is NOT required to manage the

* CLARiiON AX series array.

------------------------------------------------------

Installation of was successful.

9.Register PowerPath on the host

If you have previously registered an earlier version of PowerPath on

the host, PowerPath will use your old key; you need not reregister.

However, if your previous registration was for evaluation purposes,

and the registration has expired, you must reregister before youreboot the host.

Registering PowerPath after you install the software and before you

reboot the host sets the appropriate default load balancing and

failover policy.

Note:Rebooting before registering PowerPath

If you reboot the host before you register PowerPath:

1. Run the powermt set policy command to reset the load balancing

and failover policy.

2. Run powermt save to save the settings in the powermt.custom

file.

10.To register the PowerPath software:

1. Type /etc/emcpreg -install

Output similar to the following appears:

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

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

2. Type y and press Enter.


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. Type the PowerPath registration key and press Enter. You can

also add keys for other technologies, such as PowerPath

Migration Enabler or PowerPath Encryption with RSA.

If you typed a valid key, output similar to the following appears:1 key(s) successfully added.

Key successfully installed.

Key (Enter if done):

4. When you have finished typing keys, press Enter. You will see the

following output if you typed one key:

1 key(s) successfully registered.

11.If you are registering PowerPath on a Solaris 10 host, perform

these additional steps. Otherwise, proceed to the next section.

c. Run the powermt set policy command to reset the load

balancing and failover policy.

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

12.Reboot the host

If you are installing PowerPath for the first time and are prompted to

reboot, you must reboot now by typing 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.

13.To verify the PowerPath installation:

1. Type pkginfo -l EMCpower to verify that PowerPath is installedproperly on the host.


Note: When you install PowerPath on an x86 host, i386 appears in the

ARCH row.

14.Type modinfo | grep emcp to verify that the PowerPath kernel

extension is loaded on the host.

Output similar to the following appears on SPARC hosts:

Note: The emcpmp, emcpmpc, emcpmpap, and emcpmpaa extensions

present in previous releases have been replaced by the emcpmpx

extension in PowerPath 5.2 for Solaris.

15.Verify PowerPath devices are configured on the host

To verify that PowerPath devices are configured on the host in a Fibre

Channel and iSCSI environment:

1. Type powermt display dev=all

Output similar to the following appears for each device in a Fibre

Channel environment:

Pseudo name=emcpower0a

Symmetrix ID=000000003269

Logical device ID=048
