Monitor cluster status

Taking appropriate actions when necessary, the cluster resource services performs basic monitoring of a cluster and its components using the reliable message function and heartbeat monitoring.

You can also manually monitor the status of a cluster and its components.

Using iSeries™ Navigator

This requires Option 41 (HA Switchable Resources) to be installed and licensed.

To monitor the status of a cluster in iSeries Navigator:

In iSeries Navigator, expand Management Central.
Expand Clusters.
Navigate within the iSeries Navigator folders for the desired cluster to view the status of the cluster, its nodes, and resources using the Status column in the iSeries Navigator list. The online help contains descriptions of the possible values for the Status column. You can also right-click on components of the cluster and select Properties to view information about the cluster.
