Clustered Data ONTAP MetroCluster: Node Interconnect Redundancy Monitor

DataONTAP.Cluster.MetroCluster.Node.InterconnectRedundancyMonitor (UnitMonitor)

The MetroCluster Node Interconnect Redundancy Monitor checks the configured number of interconnect connections, including DR and HA connections. In a normal state, the number of redundant connections should be two HA connections and two DR connections.

Summary

Resolutions

Inspect the contents of the alert to determine its cause. Check the MetroCluster interconnect configuration using the clustered Data ONTAP metrocluster interconnect show command. In a normal state, the number of redundant connections should be two for each type of connection. If the number of connections differs, the MetroCluster configuration might be in a switchover state or there is a connection problem with the cable.
