That doesn't mean you can't umount it from the command line:
# umount /path/to/mount/point

As commented in another thread the other day, you probably want to do
a "clusvcadm -Z servicename" to stop RHCS from taking action if you
manage to umount the filesystem. Don't forget to do "clusvcadm -U
servicename" afterwards...
