NOTE: Upgrade the server with the highest IP address first. Then
continue to upgrade the servers in descending order of IP address.
1. Stop HP Clustered File System on the server to be upgraded. (Either
issue the command net stop matrixserver from the Command
Prompt, or stop the product via the Microsoft Management Console
Services snap-in.)
2. Back up the cluster configuration as described under “Back Up the
Existing Cluster” on page 5.
3. Remove all HP Clustered File System and FS Option for Windows hot

Programs interface to do this.

configuration.” You will need to reboot the server when the “reboot”
popup message appears.
NOTE: Do not use the Add/Remove Programs “Remove” option on
the Control Panel to remove HP Clustered File System. This
method will remove your cluster configuration. If you want to
use Add/Remove Programs to remove HP Clustered File
System, use the “Change” option and then select “Keep the
existing HP Clustered File System configuration.”
