As long as you are replicating at the VDM level and not the filesystem level, your servers and shares should move over with the replication.  If you only replicated the filesystems and not the VDM, you will need to recreate any shares and servers you would need on the destination side.

Thanks.

We are replicating VDM aswell.

what need to be done if I wanted to conduct a DR test only for a single file system under a VDM without interrupting other file systems operations on production side if the VDM replication is already in place.

While managed via Replicator, it is all-or-none in regards to the VDM and the filesystems, CIFS server, and shares associated with it.  However, you could consider presenting a checkpoint of the target filesystem and present that via a separate CIFS server (on the physical data mover) as described in the both of the following KB article:

emc216579: "How to conduct an application test on destination side without stopping replication sessions"

emc146081: "Celerra IP Replication: How do I  access through CIFS replicated read-only data at the Disaster Recovery site?"

Thanks. below is test plan I prepared for our environment for DR testing. Can someone review it and comment

1. Validate the current replication setting for VDM and filesystem, and do a ping test on the CIFS server.
2. Stop VDM replication on the PROD side:
   nas_replicate -stop id= -mode both
3. Stop filesystem replication on the PROD side:

nas_replicate -stop id= -mode both

1. Set the PROD VDM to mounted state:
   nas_server –vdm –setstate mounted
2. Set the PROD filesystem to read-only state (to prevent writes during the testing period):
   server_mount –o ro
3. Set the PROD interface to down state:
   server_ifconfig down
4. On the DR side, set the COB VDM to loaded state:
   nas_server –vdm –setstate loaded
5. On the DR side, set the COB filesystem to mounted and read/write:
   server_mount -o rw
6. On the DR side, set the DR interface to up state:
   server_ifconfig up
7. Do a ping test of the CIFS server FQDN to ensure that the NAS is back up via the COB interface.
8. Wintel administrator need to validate that share is accessible.
