If you need to install the 3.6.0 release in a different location, copy the
backup configuration files (see “Back Up the Existing Cluster” on
page 5) to that location before installing HP Clustered File System
3.6.0.
Upgrade Considerations
When upgrading HP Clustered File System, you should be aware of the
following:
The server with the numerically highest primary IP address must be
upgraded first. Then continue to upgrade the servers in descending
order of IP address, with the server with the lowest primary IP
address being upgraded last.
If a server is temporarily out of the cluster during the upgrade (for
example, for maintenance), you will need to upgrade it to 3.6.0 before
returning it to the cluster.
The stand-alone HP CFS Management Console, which is used to
connect to the cluster from hosts not running the cluster software,
must be upgraded to the 3.6.0 version.
If you are upgrading to the 64-bit operating system, be sure to install
the 64-bit version of the HBA driver and the 64-bit version of HP
Clustered File System and FS Option for Windows.
Rolling Upgrade Procedures
The rolling upgrade procedure does not require any cluster downtime.
Each server is removed from the cluster, upgraded, and then returned to
the cluster.
There are two procedures:
Upgrade HP Clustered File System and reinstall the operating system.
See page 10.
Upgrade HP Clustered File System without reinstalling the operating
system. See page 12.
