VNXe to Celerra Replication Failback
I just received a VNXe 3100 and setup replication to an NS-120.
I am able to failover to the NS-120 and mount a CIFS server to the FileSystem. The issue I am having is with Failback option.
The replication shows status "Switched Over" on the NS-120 and cannot be started. Replication options are grayed-out on the VNXe.
Null,
From the NS-120 the recovery process is two steps. First start the session from the NS-120 using nas_replicate -start with the -reverse option. Then issue a nas_replicate -reverse to flip the session back to the original state.
That should restore your source to read-write and the destination to read-only.

On the NS-120 in Unisphere, START was the only option available. Using the command line, I was ran the nas_replicate -start with the -reverse option as Tyler discussed. This got me going!!! Thanks for the quick response!

If you highlight the replication session that says "switched over" in Unisphere on the NS-120, are all the buttons on the bottom grayed out? Can you view the properties of the session? To get this session back to normal, you need to start the replication relationship and then initiate a Reverse from the NS-120.
