Hi, thanks for the reply. But I would like to know what does the "switch" parameter refer to during the configuration of the node. Somehow, I have a feeling it might be this parameter causing the fencing problem. As for my configuration, when my application fails over to node2 (by "downing the network on node1), would node1 reboot or just shutdown? Finally, I've checked the /var/log/messages. No fencing is done at all, as indicated from the log messages. Any help on this would really be appreciated.
