I have two Netapp filers running ONTAP 7-mode with some volumes on the main one replicated to the secondary one on another site. I need to regularly test my DR, but I can't break the replication during the test. Sometimes they're quite long, and a lot of changes happen to the main system's replicated volumes that would be lost, if we had a real DR during a DR test. Also, I'd risk falling behind by a couple of days of replication, which could take a lot longer to catch up on.
I want to clone the replicated volumes to test them, however the snapmirror targets are read-only, so I can't take a snapshot for the clone.
