HP StoreAll OS 6.5.1 Upgrade Guide

3. Run the following command to verify that automated failover is off. In the output, the HA column
should display off.
<ibrixhome>/bin/ibrix_server -l
4. 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.
5. If file systems are mounted from a Windows StoreAll client, unmount the file systems using the
Windows client GUI.
6. Unmount all StoreAll file systems:
<ibrixhome>/bin/ibrix _umount -f <fsname>
Saving the node configuration
Complete the following steps on each node, starting with the node hosting the active management
console:
1. Run /usr/local/ibrix/setup/save_cluster_config. This script creates a tgz file
named <hostname>_cluser_config.tgz, which contains a backup of the node
configuration.
2. Save the <hostname>_cluser_config.tgz file, which is located in /tmp, to the external
storage media.
