Hello all, |HP iLO is supported as a fencing device. If you are serious, |you should still consider power fencing (don't forget, that |fencing can be a SPOF, you need two fencing devices).
ILO is used on many sites successfully. |iLO/IPMI fencing has some serious consequences: |- It's not a shared device. It MUST be on the same network path as | heartbeat. Not true... I have my ILO on my public network and my heartbeat on a private network switch. No problems with fencing in this configuration. |- Server out of power = iLO out of power. After a recent update of cman | in RHEL5.2, rgmanager now waits for fencing to complete before | starting any services. If one node is offline (away for repair, etc.) | then it's fencing will never complete and you are stuck. I have some ILO issues to be fixed in RHEL-5.3 for fencing on blades... The situation I have seen is you must be successful in power off and power on for the ILO fence to complete as you suggest. I hope this will would be changed and that a ILO power off would be sufficient. In the case of "away for a planned repair" you would not perform an ILO fence, rather you would shutdown the node in the cluster gui. I hope this helps.
