6.0 HP X9320 Network Storage System Administrator Guide (AW542-96009, December 2011)

1. Apply any custom tuning parameters, such as mount options.
2. Remount all X9000 Software file systems:
ibrix_mount -f <fsname> -m </mountpoint>
3. From the node hosting the active management console, run the following upgrade script:
/usr/local/ibrix/setup/post_manualupgrade
This script turns automated failover back on, performs a backup of the upgraded configuration,
verifies versions, and verifies the health of the cluster. If the management console was in
maintenance mode on any file serving nodes, the console is moved to passive mode. The
script also ensures that the management console is available on all file serving nodes and
installs the management console in passive mode on any dedicated Management Servers.
4. Upgrade Linux X9000 clients. See “Upgrading Linux X9000 clients” (page 90).
5. If you received a new license from HP, install it as described in the “Licensing” chapter in this
document.
6. Run the following command to rediscover physical volumes:
ibrix_pv -a
7. Start any Remote Replication, Rebalancer, or data tiering tasks that were stopped before the
upgrade.
8. If you are using CIFS, set the following parameters to synchronize the CIFS software and the
management console database:
• smb signing enabled
• smb signing required
• ignore_writethru
Use ibrix_cifsconfig to set the parameters, specifying the value appropriate for your
cluster (1=enabled, 0=disabled). The following examples set the parameters to the default
values for the 6.0 release:
ibrix_cifsconfig -t -S "smb_signing_enabled=0,
smb_signing_required=0"
ibrix_cifsconfig -t -S "ignore_writethru=1"
The SMB signing feature specifies whether clients must support SMB signing to access CIFS
shares. See the HP X9000 File Serving Software File System User Guide for more information
about this feature. Whenignore_writethru is enabled, X9000 software ignores writethru
buffering to improve CIFS write performance on some user applications that request it.
9. Mount file systems on Linux clients.
Upgrading Linux X9000 clients
Be sure to upgrade the cluster nodes before upgrading Linux X9000 clients. Complete the following
steps on each client:
1. Download the latest HP X9000 Client 6.0 package.
2. Expand the tar file.
3. Run the upgrade script:
./ibrixupgrade -f
The upgrade software automatically stops the necessary services and restarts them when the
upgrade is complete.
4. Execute the following command to verify the client is running X9000 software:
/etc/init.d/ibrix_client status
IBRIX Filesystem Drivers loaded
IBRIX IAD Server (pid 3208) running...
