About stopping a cluster or a node
Shutting down a cluster differs from stopping a node in a cluster. To shut down a a node, from the node’s Configuration Console, on System—Status, choose Stop. When you stop a node, the following events occur:
The node leaves the cluster.
The services and resource groups on the node are no longer available to the cluster.
The status of the node changes to offline.
To shut down a cluster, you shut down all the nodes forming the cluster.
