HP StoreAll OS 6.5.1 Upgrade Guide

Agile offline upgrade
This upgrade procedure is appropriate for major upgrades. Perform the agile offline upgrade in
the following order:
• Node hosting the active management console
• Node hosting the passive management console
• Remaining nodes
NOTE: To determine which node is hosting the active management console, run the following
command:
<ibrixhome>/bin/ibrix_fm -i
Preparing for the upgrade
1. On the active management console node, disable automated failover on all nodes:
<ibrixhome>/bin/ibrix_server -m -U
2. Verify that automated failover is off. In the output, the HA column should display off.
<ibrixhome>/bin/ibrix_server -l
3. On the active management console node, stop the NFS and SMB services on all nodes to
prevent NFS and SMB clients from timing out.
The following steps are strongly recommended for shutting down processes in a proper manner
as to prevent data loss:
IMPORTANT: Alert users that SMB (CIFS), NFS and NDMP processes will be stopped for
proper cluster shutdown. Improper shutdown might result in file inconsistencies.
a. To stop SMB (CIFS) processes:
ibrix_server -s -t cifs -c stop
b. If you are using SMB, verify that all likewise services are down on all nodes:
ps -ef | grep likewise
Use kill -9 to stop any likewise services that are still running.
c. To stop NFS processes:
ibrix_server -s -t nfs -c stop
Verify that all NFS processes are stopped:
ps -ef | grep nfs
If necessary, use the following command to stop NFS services:
/etc/init.d/nfs stop
Use kill -9 to stop any NFS lockd and nfsd that are still running.
d. To stop NDMP processes:
ibrix_server -s -t ndmp -c stop
e. If necessary, run the following command on all nodes to find any open file handles for
the mounted file systems:
lsof </mountpoint>
f. Use kill -9 to stop any processes that still have open file handles on the file systems.
This step should be a last resort to stopping services. Improper shutdown might result in
file inconsistencies.
