Issue

Syncronous snapmirror is OutOfSync with below last transferred error.

Last Transfer Error: Failed to configure source. (Failed to re-establish sync usiness Continuity (SMBC) relationship. An Automatic Resync will be triggered soon. Check   snapmirhe state of sync replication)

Some other below error messages can also be seen on CG level.

Failed to configure source. (CSM: An operation failed due to an ONC RPC failure.)

Failed to configure source. (SnapMirror operation failed due to one of the following: node reboot, storage failover, storage failback, aggregate relocation, volume move or network connectivity issues. If this is a manual operation, wait a few minutes, and then try the operation again.)

Cluster peer status between destination to source cluster is in partial/pending state.

destination cluster:

cluster_dst::> cluster peer show

Peer Cluster Name Cluster Serial Number Availability Authentication

source cluster:

Cluster_src::> cluster peer show

The cluster peer ping from destination cluster is only reachable to node1 of source cluster, and unreachable to node2 source cluster
