Question about a case of creating a SnapMirror(with vaults) Cascade. I believe this is by design, though I couldn't find it in the best practices guide .
A...........B
Prod --> DR (Type: Mirror-Vault)
The DR Site has SnapMirror snapshot, and many of the Snapvault snapshots.
Then, I did a SnapMirror (Type: Mirror-Vault) to a 3rd Site, so:
A...........B..................................................C
Prod --> DR (Type: Mirror-Vault) ---> 3rd Site (Type: Mirror-Vault)
At the 3rd site, we only see the SnapMirror snapshots (2 snapshots only and it doesn't bring the snapvault snapshots from DR).
So a few questions:
1. is there a way that would bring across all in the one snapmirror relationship?
2. if i were to break A-B, then do a snapmirror update on the 3rd site, would that update and then bring the snapvault snapshots?
3. could i create a new snapmirror relationship and specify just the snapvaults to copy across from B?
I've noticed the online KB mentions to move a snapvault target, you should break A-B, then mirror B-C, then break B-C and then resync A-C. Is this still current with the current version of 9.9.x?
