There is a scheduled BCP test for a VNX file arrays. We use mirror view async for replication.
Below is high level plan
1) Perform reverse from Primary array to DR array for the vdm\file system
2) The n/w team is planning to isolate the ip n/w connectivity data-center for 4 hours, where the primary array is located. This means replication will break.
3) n/w link is brought up back up.
4) Data needs to be synced back and replication session will be reversed to primary array.
My question is when the n/w link is brought back up, will the replication automatically start to sync from DR to primary array or should there be a manual intervention issuing one of the below 2 commands ? What will be the replication sessions status ?
nas_repicate -start $repl_sessions_name or nas_replicate -start $repl_sessions_name -overwrite destination.
Wait for the sync to catch up followed by nas_replicate -reverse command.
