Thanks Xaviar. It resolved the error on fencing. However I still am grappling with issue of finding name of "Failed cluster node" on another cluster node to which service on failed node has failed over to. I was using output of "clustat -x -S service name" and was parsing XML file to obtain value of "last_owner" field. Any input on how to find out name of failed node on another cluster node, over which services from failed node are starting?
