Unwanted Snapshots are being replicated to cascade tertiary volume
Applies to
- ONTAP 9
- SnapMirror cascade deployment
Issue
- SnapMirror cascade configuration where a SnapMirror destination volume is also a source volume for another relationship
- Second hop of the cascade is a Vault with a single rule to replicate "weekly" SnapMirror labeled Snapshot copies only
- Additional Snapshot copies are also being replicated to the Vault destination volume
