If your cluster node experiences a CPU, RAM, or motherboard failure, it is an unrecoverable failure and the cluster node will go offline. The cluster fencing mechanism will fence the problematic cluster node to make sure that it is no longer running and prevent the problematic cluster node from accessing the shared cluster storage. If your cluster node experiences disk failure, it should not be affected due to RAID disk redundancy. In the event of a disk failure, the cluster node should still be operational.

The cluster from the following example is configured to provide a WebSite resource group that includes a cluster IP address and Apache webserver instance. The WebSite resource group is running on the node-1.geekpeek.net cluster node. In the following screenshot, you can see the cluster status prior to the hardware failure test:

You can proceed to simulate the node-1.geekpeek.net cluster node's hardware failure. You can do this by cutting off the power of the node-1.geekpeek...
