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
