Node Status
The node status is the current status of a node relative to a particular
cluster.
The hp-mcCluster MIB variable, hpmcNodeStatus, provides the node
status information to the monitor.
The cmviewcl -v command displays detailed information about the
current status of the cluster and packages on the cluster.
You can create a request that notifies you when the local node is not
running. You can then verify whether the node or MC/ServiceGuard was
stopped intentionally.
The minimum polling interval for node status is 30 seconds. You may
want a longer interval, especially if system performance is affected.

Interpretation
RUNNING 1 Node is accessible and operating normally.
INITIALIZING 2 Node’s cluster 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.
