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
