14. Check CFS mount points.

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.
Deleting CFS from the Cluster
Halt the applications that are using CFS file systems.
1. Unmount CFS mount points.
# cfsumount /cfs/mnt1
# cfsumount /cfs/mnt2
# cfsumount /cfs/mnt3
2. Delete mount point multi-node package.
# cfsmntadm delete /cfs/mnt1
The following output will be generated:
Mount point “/cfs/mnt1” was disassociated from the cluster
# cfsmntadm delete /cfs/mnt2
The following output will be generated:
Mount point “/cfs/mnt2” was disassociated from the cluster
# cfsmntadm delete /cfs/mnt3
