Hello, We have configured an active-active two node cluster accessing a shared storage. We are using Red Hat Cluster Suite on RHEL 4Update 4. The nodes are HP Servers having ILOs as the fence devices. I am facing certain problems in the setup and would seek suggestions. While booting up the systems, many a times one node forces the other one to reboot for no reason. How do I prevent that ? We want the failover to happen when the power supply fails to either of the nodes. In order to test the scenario, we removed the power cables from one of the nodes. However the failover did not happen and upon observing the logs we found that the alive node could not connect to the fence device (ILO in this case) of the dead node since it was powered off and the fencing could not take place. Does this mean that we would not be able to have a failover in case of power failure for one of the nodes. Is there a way we can do it ? How is the cluster supposed to react when the ILO itself is powered off ? Another failover test was conducted by removing the network connectivity on of one of the nodes. Failover did happen smoothly in the dead node was rebooted by the fence device. However when the dead node was reconnected to the network, it fenced and rebooted the alive node. How to deal with this ? Thanks, Manish -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
