HP StoreAll OS 6.5.1 Upgrade Guide

5. Run the following command to rediscover physical volumes:
ibrix_pv -a
6. Apply any custom tuning parameters, such as mount options.
7. Remount all file systems:
ibrix_mount -f <fsname> -m </mountpoint>
8. Confirm changes:
ibrix_server -l
9. Force a Fusion Manager database backup:
ibrix_fm -B
10. Confirm the nodes were upgraded:
ibrix_version -l
11. Verify cluster health:
ibrix_health -l
12. Place all disabled Fusion Managers back in passive mode:
ibrix_fm -m passive -A
13. Re-enable High Availability if used:
ibrix_server -m
14. Start any remote replication, rebalancer, or data tiering tasks that were stopped before the
upgrade.
15. If you are using SMB, set the following parameters to synchronize the SMB software and the
Fusion Manager database:
• smb signing enabled
• smb signing required
• ignore_writethru
Use ibrix_cifsconfig to set the following parameters, specifying the value appropriate
for your cluster (1=enabled, 0=disabled). The following examples set the parameters to the
default values for this 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 SMB
shares. When ignore_writethru is enabled, StoreAll software ignores writethru buffering
to improve SMB write performance on some user applications that request it. See the HP
StoreAll OS User Guide for more information about this feature.
16. During upgrades and installations, the clearSegmentUnavailableUponFailover
parameter of the ibrix_fm_tune command is incorrectly set to false. To resolve this issue,
run the following command to reset the default value to true:
ibrix_fm_tune –S –o clearSegmentUnavailableUponFailover=true
17. If you have a file system version prior to version 6, you might have to make changes for
snapshots and data retention, as mentioned in the following list:
• Snapshots. Files used for snapshots must either be created on StoreAll software 6.0 or
later, or the pre-6.0 file system containing the files must be upgraded for snapshots. To
upgrade a file system, use the upgrade60.sh utility. For more information, see
“Upgrading pre–6.0 file systems for software snapshots” (page 24).
• Data retention. Files used for data retention (including WORM and auto-commit) must be
created on StoreAll software 6.1.1 or later, or the pre-6.1.1 file system containing the
files must be upgraded for retention features. To upgrade a file system, use the
ibrix_reten_adm -u -f FSNAME command. Additional steps are required before
