To view, edit, start up, or shut down your clusters, click My Clusters to see a list of your clusters. You can have more than one cluster, some running (online) and some shut down (offline). The following listing shows a pair of clusters, one currently online and ready, the other offline:
To stop a cluster, click Shut Down in the Actions column. Shutting down a cluster does not remove it from your list. You can start the cluster again at a later time. To permanently remove a cluster, click Delete. You can shut down a cluster during its startup if it fails to start, takes too long, or you change your mind.
For detailed information about a particular cluster, click its name in the list.
