Manual Upgrades; Preparing For The Upgrade; Saving The Node Configuration; Performing The Upgrade - HP StoreAll 9730 Administrator's Manual

The upgrade script performs all necessary upgrade steps on every server in the cluster and
logs progress in the file /usr/local/ibrix/setup/upgrade.log. After the script
completes, each server will be automatically rebooted and will begin installing the latest
software.
5. After the install is complete, the upgrade process automatically restores node-specific
configuration information and the cluster should be running the latest software. If an UPGRADE
FAILED message appears on the active management console, see the specified log file for
details.

Manual upgrades

The manual upgrade process requires external storage that will be used to save the cluster
configuration. Each server must be able to access this media directly, not through a network, as
the network configuration is part of the saved configuration. HP recommends that you use a USB
stick or DVD.
NOTE: Be sure to read all instructions before starting the upgrade procedure.
To determine which node is hosting the agile management console configuration, run the ibrix_fm
-i command.

Preparing for the upgrade

Complete the following steps:
1. Ensure that all nodes are up and running.
2. On the active management console node, disable automated failover on all file serving nodes:
<ibrixhome>/bin/ibrix_server -m -U
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. On the active management console node, stop the NFS and SMB services on all file serving
nodes to prevent NFS and SMB clients from timing out.
<ibrixhome>/bin/ibrix _server -s -t cifs -c stop
<ibrixhome>/bin/ibrix _server -s -t nfs -c stop
Verify that all likewise services are down on all file serving nodes:
ps -ef | grep likewise
Use kill -9 to kill any likewise services that are still running.
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.

Performing the upgrade

Complete the following steps on each node:
