Issue

  • The “InterclusterBrokenConnectionAlert” event is reported in the event logs after ONTAP upgrade or Switchover/Switchback operation:
[Node-1: schmd: hm.alert.raised:alert]: Alert Id = InterclusterBrokenConnectionAlert , Alerting Resource = Node-2 raised by monitor system-connect
[Node-1: mgwd: callhome.hm.alert.major:alert]: Call home for Health Monitor process schm: InterclusterBrokenConnectionAlert[Node-2].
  • System health alert reports the following:
Cluster1::*> system health alert show -instance
 
Node: Node-1
Monitor: system-connect
Alert ID: InterclusterBrokenConnectionAlert
Alerting Resource: Node-2
Subsystem: MetroCluster
Indication Time: Tue Nov 15 21:58:10 2022
Perceived Severity: Major
Probable Cause: Out_of_service
Description: Connectivity to peer cluster is broken.
Corrective Actions: 1) Ensure that the port is connected to the correct network/switch.
2) Ensure that the intercluster LIF is connected with the peered cluster.
3) Ensure that the peered cluster is up and running by using the command "cluster peer ping". Refer to the MetroCluster Disaster Recovery Guide if the peered cluster is down.
Possible Effect: Communication to the peer cluster is compromised and the replication of configuration between the clusters might stop.
  • MetroCluster is degraded due to this alert:
