[Pacemaker] Shared Storage

My testing two node (openais and corosync) cluster is up and running (RHEL v5.5). Now I'd like to create LVM disk storage for the cluster for failover. The cluster is attached to an EMC Symmetrix SAN. The same LUNs from the EMC Symmetrix can be seen on both nodes.
I was thinking to use DRBD for the storage management but then I found that I can't use DRBD. DRBD uses two separate storage devices for two nodes and sync them. 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? Redhat's cluster is active-active mode not HA mode and that is not I want for now. Thanks.
