Storage Migration Steps - on VVR

Hi ,

I want to migrate storage on VVR. Below are the steps I have in mind. Please guide me to do it in right way.

1. Stop the replication between DC1 & DR

2. Add the New array lun on primary site node.

3. Vxevac from Source lun to target lun. Same for SRL

4. Check the DCM for the Volume after the migration

5. Proceed the same on Secondary site and start replication

Below is the Diskgroup which I want to migrate.

rv rdu-rvg      1            ENABLED  ACTIVE   secondary 2        srl-vol
rl to_rdu-wc-ap-vvr rdu-rvg  CONNECT  ACTIVE   rdu-wc-ap-vvr rdu-dg to_rdu-po-ap-vvr

@Velmathan 

I have moved your post to a more relevant forum.

I would rather use the mirror method as described in these TNs:

Re: Storage Migration Steps - on VVR

Thanks @Marianne

I have done migration on vxvm using vxevac/mirror but here my concern is on the replication (rvg/rlink) part.

Whether I need to pause/stop replication before starting storage migration and DCM log recreation is required or not.? 

Both the site I want to perform the migration one after one. (replication need to stop or not )

This RVG are configured in Global cluster , I want to do this activity without downtime. It should not affect the service group.

Please help me on providing steps on VVR part.
