Enable the cluster services with the following command. This configures the cluster services to run on startup on the specified node or nodes.
Enabling allows nodes to automatically rejoin the cluster after they have been fenced, minimizing the time the cluster is at less than full strength. If the cluster services are not enabled, an administrator can manually investigate what went wrong before starting the cluster services manually, so that, for example, a node with hardware issues in not allowed back into the cluster when it is likely to fail again.

--alloption, the command enables cluster services on all nodes. - If you do not specify any nodes, cluster services are enabled on the local node only.
