Interpreting Node Status | HP HA s Software manual

Monitoring Cluster Resources

Cluster Monitor Reference

Node Status

		The node status is the current status of a node relative to a particular cluster.
		The MIB variable hpmcClusterState, which is part of the hp-mcCluster MIB,
		provides the node status information to the monitor.
		The cmviewcl -vcommand displays detailed information about the current
		status of the cluster and packages on the cluster.
Table 3-2		Interpreting Node Status

	Resource Name			/cluster/localNode/status/clusterName

	Condition		Value	Interpretation

	RUNNING		1	Node is accessible and operating normally.

	INITIALIZING		2	Node’s daemon has started, but is not ready to communicate with
				other nodes’ daemons.

	RECONFIGURING		3	Node is running protocols to make sure all other nodes agree to the
				new membership in the cluster.

	INVALID		4	The cluster status may be DOWN.

	HALTED		5	Node has been removed from the cluster, with the cmhaltnode
				command, for example.

	FAILED		6	Node is no longer a member of an active cluster.

You might want to create a request that notiﬁes you when the local node is not running. You can then verify that the node or MC/ServiceGuard was stopped intentionally.

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