Well if you have a SAN, and only want it mounted on one machine at a
time... then do you actually need any?
Even if so, then the "under Pacemaker" part is irrelevant - since
Pacemaker would have no interaction with it.

The storage that I have is the one shared by both nodes. HP's HPUX MC/Services shares storage on both nodes. What do I need for Pacemaker for HA mode to have one shared storage?
