I have 2 HP DL 380 G6 Servers having OS installed RHEL 5.4 AP. I have setup RHEL Cluster suite for HA and I am using HP ILO2 as a fencing device. Cluster service is working fine and fencing also working fine. Now the problem comes when one day one of the active node's power got failed the cluster service was not able to relocate on second passive node. When I executed clustat in passive node for checking cluster service it shows it is still running on Active node. Why this happen is RHEL 5 cluster service is not designed for cop-up with power failure situation. Please guide.
