3.7.0 HP StorageWorks HP Scalable NAS File Serving Software upgrade guide HP Scalable NAS for Linux (AG513-96005, October 2009)

20. Change the HBA driver if necessary. HP Scalable NAS includes several versions

of the HBA drivers for the supported FC host bus adapters. For each host bus

adapter, one driver version is designated as the default in the /etc/opt/

hpcfs/fc_pcitable file. If you require a different driver version (a version

included with HP Scalable NAS or from another source), you can install that

driver version in place of the HP Scalable NAS default version. For more

information, see “Host Bus Adapters (HBAs)” in the HP Scalable NAS File Serving

Software administration guide. Although the procedure in the administration

guide instructs you to start HP Scalable NAS, do not start the product until you

are asked to do so later in the upgrade. If you need to enable the failover feature

on the QLogic HBA driver, see Chapter 6 in the administration guide.

NOTE:

The /etc/hba.conf file must point to the correct hbaapi library.

21. If you installed an HBA driver in the previous step, run the following command

to load it:

# /etc/init.d/pmxs load

Then run the following command to see a list of devices and review the output

to verify that the SAN is configured as you expect.

# cat /proc/partitions

22. Check the mount points for the PSFS filesystems on the server, and recreate them

if necessary to match the other servers.

23. Start HP Scalable NAS on the upgraded server. Run this command:

# /etc/init.d/pmxs start

24. Re-enable the server. (Select the server on the Management Console, right-click,

and select Enable.)

HP Scalable NAS is now running on the server; however, NFS services will not be

available until all cluster nodes are upgraded to 3.7.0 and the new mxds datastore

is operational.

Upgrade the remaining servers

Complete this procedure on the remaining servers. You can upgrade the servers

one-at-a-time or all-at-once.
