Manual Upgrades; Standard Upgrade For Clusters With A Dedicated Management Server Machine Or Blade; Standard Online Upgrade - HP IBRIX X9720 System Administrator Manual

Manual upgrades

Upgrade paths
There are two manual upgrade paths: a standard upgrade and an agile upgrade.
The standard upgrade is used on clusters having a dedicated Management Server machine
or blade running the management console software.
The agile upgrade is used on clusters having an agile management console configuration,
where the management console software is installed in an active/passive configuration on
two cluster nodes.
To determine whether you have an agile management console configuration, run the ibrix_fm
-i command. If the output reports the status as quorum is not configured, your cluster
does not have an agile configuration.
Be sure to use the upgrade procedure corresponding to your management console configuration:
For standard upgrades, use
For agile upgrades, use
Online and offline upgrades
Online and offline upgrade procedures are available for both the standard and agile upgrades:
Online upgrades. This procedure upgrades the software while file systems remain mounted.
Before upgrading a file serving node, you will need to fail the node over to its backup node,
allowing file system access to continue. This procedure cannot be used for major upgrades,
but is appropriate for minor and maintenance upgrades.
Offline upgrades. This procedure requires that you first unmount file systems and stop services.
(Each file serving node may need to be rebooted if NFS or CIFS causes the unmount operation
to fail.) You can then perform the upgrade. Clients will experience a short interruption to file
system access while each file serving node is upgraded.
Standard upgrade for clusters with a dedicated Management Server machine or
blade
Use these procedures if your cluster has a dedicated Management Server machine or blade hosting
the management console software. The X9000 Software 5.4.x to 5.5 upgrade can be performed
either online or offline. Future releases may require offline upgrades.
NOTE: Be sure to read all instructions before starting the upgrade procedure.

Standard online upgrade

The management console must be upgraded first. You can then upgrade file serving nodes and
X9000 Clients in any order.
Upgrading the management console
Complete the following steps on the Management Server machine or blade:
1. Disable automated failover on all file serving nodes:
<ibrixhome>/bin/ibrix_server -m -U
2. Verify that automated failover is off:
<ibrixhome>/bin/ibrix_server -l
In the output, the HA column should display off.
