italics change depending on the names of the clusters and packages on
the system.
Cluster Status
The cluster status is the status of the MC/ServiceGuard cluster to which
this node belongs.The status is from the perspective of the node forwhich
the request was created.
The hp-mcCluster MIB variable, hpmcClusterState, provides the
cluster status information to the monitor.
The cmviewcl -v command displays detailed information about the
current status of the cluster and packages on the cluster.
