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 -v command displays detailed information about the current
status of the cluster and packages on the cluster.
Table 3-1 Interpreting Custer Status
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.
Resource Name /cluster/status/clusterName
Condition Value 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.
