Don't do that. :) They're *supposed* to try to fence each other in this case. However, the one with the disconnected network jack will lose - because it should not be able to talk to DRAC. > Suppose, I would like to check whether the router can be pinged before I fence the peer node. Is it a possible configuration in using Red Hat Cluster Suite? You can use qdisk to add any sort of heuristic you want for a node to determine liveliness fitness. See the qdisk man page out of the RHEL4 branch. -- Lon -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
