Guys, thanks a lot for your input. I have a doubt related to IPMI fencing. In IPMI fencing, we specify network address of IPMI controller. This is out of band network address as well as IPMI board must have power supply different from cluster node. Am I right? Thanks in advance for your help.

Oh! that was me): 1. Don't commit support for manual fencing 2. Don't support manual fencing. If you are in India, APC Fence PDU is available for around 30-35K INR (about a year back or so). If someone is ready to invest say 500K INR for HA hardware such as two servers etc., they might as well add 35k. OTOH, if those nodes are rack mounted servers (Unlike entry level server which does not have management port), the cost of the Powerfence strip will be a different issue when it comes to justifying, etc. within a corporate/Enterprise environment. Too much paperwork, I agree. But It will give a more robust infrastructure which will help us in using various tools like Zabbix, Spacewalk, snmp (I think fence strips have some SNMP - please check) etc. in the future. Life will be good then.
