SnapMirror fails with network error CSM An operation did not complete within the specified timeout window
Applies to
- Ontap 9.x
- SnapMirror
Issue
- SnapMirror updates for particular relationship always fail with an error
Transfer failed. (Replication operation request failed from "Cluster Id", "Node Id" to "Cluster Id", "Node Id" due to a network error (CSM: An operation did not complete within the specified timeout window.))
- Restarting the update with cleaning checkpoints fails with the same error on the same amount of data transferred
- Other SnapMirror relationships between same clusters/vserver may work fine
- In some cases modifying the relationship too -type DP, transfer works fine
