Summary

The Node HA State Monitor monitors the OnCommand event log for events generated by the Node HA State Monitoring Rule and generates corresponding Operations Manager alerts.

Resolutions

Inspect the contents of the alert to determine its cause. Note: If the Clusters are not configured for High Availability, like in the case of the MetroCluster 1x1 node configuration, please disable the "Node High Availability State Monitoring Rule", so the warning alert will not be generated.
