nodes. The management console is in active mode on the node where the upgrade was run,
and is in passive mode on the other file serving nodes. If the cluster includes a dedicated
Management Server, the management console is installed in passive mode on that server.
5. Upgrade Linux X9000 clients. See “Upgrading Linux X9000 clients” (page 90).
6. If you received a new license from HP, install it as described in the “Licensing” chapter in this
guide.
After the upgrade
Complete the following steps:
1. Run the following command to rediscover physical volumes:
ibrix_pv -a
2. Apply any custom tuning parameters, such as mount options.
3. Remount all file systems:
ibrix_mount -f <fsname> -m </mountpoint>
4. Re-enable High Availability if used:
ibrix_server -m
5. Start any Remote Replication, Rebalancer, or data tiering tasks that were stopped before the
upgrade.
6. 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.
7. Mount file systems on Linux X9000 clients.
Offline upgrades for X9000 Software 5.5.x to 6.0
The upgrade from X9000 Software 5.5.x to 6.0 is supported only as an offline upgrade. Because
it requires an upgrade of the kernel, the local disk must be reformatted. Clients will experience a
short interruption to administrative and file system access while the system is upgraded.
There are two upgrade procedures available depending on the current installation. If you have an
X9000 Software 5.5 system that was installed through the QR procedure, you can use the automatic
upgrade procedure. If you used an online upgrade procedure to arrive at your X9000 Software
5.5 system, you must use the manual procedure. To determine if your system was installed using
the QR procedure, run the df command. If you see separate file systems mounted on /, /local,
