Using Serviceguard Extension for RAC, 9th Edition, September 2010
NOTE: The diskgroup and mount point multi-node packages (SG-CFS-DG_ID# and
SG-CFS-MP_ID#) do not monitor the health of the disk group and mount point. They check
that the application packages that depend on them have access to the disk groups and mount
points. If the dependent application package loses access and cannot read and write to the
disk, it will fail. However, the DG or MP multi-node package will not fail.
13. Mount cluster filesystem.
# cfsmount /cfs/mnt1
# cfsmount /cfs/mnt2
# cfsmount /cfs/mnt3
14. Check CFS mount points.
# bdf | grep cfs

CAUTION: Once you create the disk group and mount point packages, you must administer
the cluster with CFS commands, including cfsdgadm, cfsmntadm, cfsmount, and cfsumount.
You must not use the HP-UX mount or umount command to provide or remove access to a
shared file system in a CFS environment. Using these HP-UX commands under these
circumstances is not supported. Use cfsmount and cfsumount instead.
If you use the HP-UX mount and umount commands, serious problems could occur, such as
writing to the local file system instead of the cluster file system. Non-CFS commands could cause
conflicts with subsequent CFS command operations on the file system or the Serviceguard
packages, and will not create an appropriate multi-node package—cluster packages will not be
aware of file system changes.

Halt the applications that are using CFS file systems.
1. Unmount CFS mount points.
# cfsumount /cfs/mnt1
