HP StorageWorks Clustered File System (software-only) 3.6.1 Windows Storage Server Edition upgrade guide (T4422 - 96001, August 2008)

Non-Rolling Upgrades

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.

If you perform a custom installation of HP Clustered File System 3.6.1

and specify a new location for the cluster software, the Installer will not

be able to locate the existing configuration files. To avoid this problem,

take one of these steps:

• If HP Clustered File System is currently installed in a custom location,

install HP Clustered File System 3.6.1 in the same location.
