See page 18.
Upgrade HP Clustered File System without reinstalling the operating
system. See page 22.
Upgrade HP Clustered File System and Reinstall the
OS
To minimize overall downtime, divide your servers into two groups and
then upgrade one group at a time while the other group runs the cluster.
The upgrade procedure assumes that the servers are divided into group
A and group B.
If you prefer to upgrade all servers at once, be sure to take the following
steps to retain the cluster configuration:
Leave one server running the old operating system and cluster
software. You can shut down the other servers as indicated below.
After the first server is upgraded to the new operating system and
cluster software, restore the cluster configuration directory from
backup.
Upgrade all remaining servers, including the server running the older
software, and export the cluster configuration to them (as in step 15).
To perform the upgrade, complete the following steps.
NOTE: Upgrade the server with the highest IP address first. Then
continue to upgrade the servers in descending order of IP address,
with the lowest numbered server being upgraded last.
1. Stop HP Clustered File System on the servers in group A. (Either issue
the command net stop matrixserver from the Command Prompt, or
stop the product via the Microsoft Management Console Services
snap-in.)
