Chapter 2: Overview 10
Back Up the Cluster Configuration
The HP Clustered File System service should not be running when you
perform the backup. The default location for the cluster configuration
files is C:\Program Files\Hewlett-Packard\HP Clustered File System\conf on
the drive where you installed HP Clustered File System. Back up the
following from the conf directory:
• The files directly under \conf
•The \conf\debug subdirectory
Do not back up the mounts and licenses subdirectories.
Upgrade Scenarios
There are three ways to perform the upgrade to HP Clustered File System
3.6.1 and FS Option for Windows
• Perform a rolling upgrade. In this procedure, servers are removed
from the cluster, upgraded, and returned to the cluster one-at-a-time.
No downtime is required. See Chapter 3, “Rolling Upgrades” on page
11.
• Upgrade all servers at once. This procedure requires that the cluster be
completely shut down during the upgrade. See Chapter 4, “Non-
Rolling Upgrades” on page 20.
• Upgrade the servers in two groups. This method minimizes overall
downtime. See Chapter 4, “Non-Rolling Upgrades” on page 20.
