I need to work on a customer cluster setup. I'll go with corosync/pacemaker. I need to setup fencing but all "I" (read: the customer) can offer is IPMI. I am worried about not being able to fence nodes when the power cable is unplugged. Does anybody have knowledge about IBM IMM ipmi board and can tell me if it has battery backup unit to provide some power at least for a limited amount of time so I can expect fencing agent to complete its tasks? or does it exist as an hardware upgrade on some product lines?
Thanks in advance
