Overview of Administering the Cluster

Language:

This section describes how to perform administrative tasks for the entire global cluster or zone cluster. The following table lists these administrative tasks and the associated procedures. You generally perform cluster administrative tasks in the global zone. To administer a zone cluster, at least one machine that will host the zone cluster must be up in cluster mode. All zone cluster nodes are not required to be up and running; Oracle Solaris Cluster replays any configuration changes when the node that is currently out of the cluster rejoins the cluster.

Note - By default, power management is disabled so that it does not interfere with the cluster. If you enable power management for a single-node cluster, the cluster is still running but it can become unavailable for a few seconds. The power management feature attempts to shut down the node, but it does not succeed.

In this chapter, phys-schost# reflects a global-cluster prompt. The clzonecluster interactive shell prompt is clzc:schost>.
