Issue

System health alert "InterclusterBrokenConnectionAlert" triggered intermittently in 4/8 -node Fabric-attached MetroCluster configuration.
Note: Alert is false and can be ignored when auto-cleared within 5 minutes
Example:
cluster_A::> system health alert show
Node: node_A1
Resource: node_A1
Severity: Major
Indication Time: Mon Dec 02 20:40:47 2019
Suppress: false
Acknowledge: false
Probable Cause: Connectivity to peer cluster is broken.
Possible Effect: Communication to the peer cluster is compromised and
the replication of configuration between the clusters
might stop.
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.
