MetroCluster aggregate mirror configuration monitor

DataONTAP.MetroCluster.MirrorConfig.Monitor (UnitMonitor)

DataONTAP.MetroCluster.MirrorConfig.Monitor monitors the OnCommand event log for events generated by DataONTAP.MetroCluster.Monitoring.Rule.Aggregates and generates corresponding Operations Manager alerts.

Knowledge Base article:

Summary

Causes

One or more aggregates are not configured as mirrors. Any non-mirrored aggregate may not be available after a cluster-failover-on-disaster occurrence.

Resolutions

To maximize availability in a disaster scenario, all aggregates in a MetroCluster should be mirrored.
