create read/write snapshot on DR array and export that to your users, no need to stop replication.

Here my doubt is, if we are starting the Replication from DC, the changes done at DR will get discarded or not. Kindly suggest

=> if you start the replication from DC then changes at DR site will get discarded.

We did DR drill test and here is our steps:

1. Host IO stopped at DC site and then final incremental update initiated

2. We planned to run the set-up two days from DR site and the changes made from DR needs to be replicated to DC. So, we promoted secondary mirrors and we ran the set-up from there next two days. In this phase, incremental updates happened from new DC (old DR) to new DR (old DC).

3. Again we stopped host IO in new DC end and promoted the secondary images.

4. DC and DR site came as before the drill activity.

Note:  (as per Primus/Webtop solution ID:emc307336)

When you promote a secondary image, the new secondary (old primary) is automatically set to manual

recovery. This is how the promotion feature works. If you want auto recovery, you must change the mirror

properties after the promotion. Changing the recovery policy from manual to auto for the secondary image

ensures that the next promotion will not start a full synchronization.

Hope this helps.

Is this possible to create read write SNAP shot (Check point) on VNX Gen 1 array

yes. you can create snapshot and attach that snapshot to a "snap mount point". Then map the SMP to DR hosts.

yes

you realize the original poster is asking about NAS and Replicator while you are talking SAN and MirrorView ?

The given steps are helpful. But we are planning for a test DR drill now, which will not interrupt users or production environment. so we are suppose to do the changes only at DR Luns or DR snapshots.

he gave you instructions for MirroView, you are using VNX Replicator right ?

Yes we are using VNX replicator

review VNX Snapsure documentation, how to create read-write snapshots.
