Monitoring Cluster Resources

Cluster Monitor Reference

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 for which the request was created.

The MIB variable hpmcClusterState, which is part of the hp-mcCluster MIB, provides the cluster status information to the monitor.

The cmviewcl -vcommand displays detailed information about the current status of the cluster and packages on the cluster.

Interpretation

 

 

 

 

 

UP

1

The node can access the cluster.

 

 

 

 

 

UNKNOWN

2

The node may be separated from other active cluster elements (for

 

 

 

example the heartbeat LAN) and has insufficient information to tell if the

 

 

 

cluster is accessible.

 

 

 

 

 

DOWN

3

The node cannot access the cluster.

 

 

 

 

You might request to be notified when the cluster is not up. You could then verify that the cluster was shut down intentionally.

The minimum polling interval for cluster status is 30 seconds. You may want a longer interval, especially if system performance is affected.
