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 -v command displays detailed information about the current
status of the cluster and packages on the cluster.
Table 3-2 Interpreting Node Status
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.
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.
