Customer is currently running Oracle DB on 3PAR. They take snapshot to the DB data and then write the archive log into the Snapshot to make sure Snapshot is ok. After writing DB +archive log, it will be mirror to DR site.
In NetApp A800 case, as Snapshot is read-only, which means we have to clone to Flexclone in order to make Snapshot writable. However question is how to restore using Flexclone (as LUN number may change), and does it require to mirror all the data again to DR site after FlexClone is restored?
We propose 2 solutions
1. Treat Archive Log as another volume and Snapshot again (customer doesn't accept to manage 2 volumes)
2. Proof with Oracle documents saying Oracle Begin Backup is not necessary
3. Ways to restore with Flexclone without re-syncing all data to DR
