Upgrading to HP Serviceguard 11.17 with Cluster Volume Manager/Cluster File Systems, December 2005

If a CFS bundle is installed and CFS is not used, the application package can be managed in a
similar way to Serviceguard A.11.16. The new SMNP must be configured. This can be done with the
cfscluster command, which is part of the bundle.

An application package can be upgraded to use the dependency infrastructure even if CFS is not
used. The new commands cfscluster and cfsdgadm are used to configure and manage storage
in this scenario.
