The cluster control software determines the health of the servers by periodically probing the servers using the monitor scripts. When the cluster control software determines that one of the servers in the cluster has failed, it will shut down that server and start the server on the spare node.

You must incorporate the UNIX shell scripts for starting, stopping, and monitoring the servers in the cluster control software's infrastructure. You might have to customize code to enable the cluster control software to invoke these UNIX shell scripts.
