Non-Rolling Upgrades
NOTE: Before starting the upgrade process, follow the steps in the new
Entitlement Certificate to obtain a license for the 3.6.0 code. There
are no temporary licenses embedded in the 3.6.0 code, so you
must obtain a new 3.6.0 license. By following the steps in the
Entitlement Certificate, you will have all necessary components
for the upgrade, which should allow you to more quickly
complete the upgrade process.
Overview
If you are not performing a rolling upgrade, you can use one of the
following methods to upgrade the cluster:
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. This method minimizes downtime.
Upgrade all servers at once.
.Upgrades are supported from HP Clustered File System 3.4.0 and FS
Option for Windows 3.4.0.
Custom Installations of HP Clustered File System
When you upgrade HP Clustered File System, the Installer looks for the
cluster configuration files in the location where HP Clustered File System
is currently installed and then applies the configuration files to the new
installation.
