Do we need to stop CVM cluster on Prod end to perform DR test

Spoiler

We have CVM (Active - Active) two node Cluster which is running on RHEL 7 and need to perform DR test, so do we need to stop the cluster on the production end before import the disk group on the DR side ? Kindly advise on that.

Note: while perform the DR test  will break the storage replication and network isolation on the production side as well.

This is very much dependent on what do you want to "test" in your DR test.

A true DR test should be conducted when the system is in "normal operation" during a scheduled maintenance window,
