Monitoring Cluster Resources
Cluster Monitor Reference
Package Status
The package status is the status of each package running on this node.
The hp-MCCluster MIB variable, hpmcSGPkgStatus, provides the
package 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 might want to be notified when the value of any of the packages
changes to UNKNOWN or DOWN, so you can verify that
MC/ServiceGuard successfully migrated the package to another system.
You may see many packages with UNKNOWN status. This is because
only the node running a package has complete status for a package.
Other nodes often have inactive volume groups that make it impossible
to have complete knowledge of package status. If a package is running on
another node in the cluster, the current node may not have complete
status on that package, and reports the condition UNKNOWN.
The minimum polling interval for package status is 30 seconds. You may
want a longer interval, especially if system performance is affected.

UP 1 The package is running on the local node.
UNKNOWN 2 The package is not running on the local node, but may be
running on another node in the cluster.
DOWN 3 The package is not running on any node in the cluster.
