CONTAP-109525: Fanout relations on SMBC volumes are failing with error "Invalid Base Snapshot"
Issue
Fan-out relationships from source volume with SM-BC and async-mirror (mirror-vault policy) receive an intermittent error on the async-mirror relationships. Example: Error: Failed to get information for source volume "SVM:volume" for setup of transfer. (Failed to start transfer as SnapMirror found an invalid base snapshot. Use the "snapmirror resync" command to recover from the failure.)
