How to switch over to DR and then Back to Main Site
Hello All,
we are using RP for block replication.we are in the process of testing the DR site.would like to know how can go back to primary site?since the data is very critical data should be consitant.
The lun size is 600GB.After switching to DR,users will be updating data after switching to DR.after testing for few hours we need to go back to primary site.changes will be less than 20% of journal space.In this case do we need to start the the replication from the beginning?I mean reverse replication.Or is it possible to replicate the changes alone to primary?
Any Help..

1. Enable image access at the DR site
2. Verify the image on the DR site and make sure that's the image you want to work with
3. Failover to DR site. I can't recall if you have to start replication or if Failover does it for you. I believe failover will start replication but not 100% certain. Before you perform the failover make sure you unmount the filesystems at the PROD site
4. Start replication from DR to PROD (if Failover didn't do this already)
5. Wait until the data is replicated from DR to PROD
6. Perform above steps 1-4 at the PROD site
