SnapView required for SRM and MirrorView
Was just thinking about the process of SRM with MirrorView /S on a VNX/CX. Would SnapView be required for a customer who wants the ability to execute a test of the recovery plan in SRM? I'm assuming it would, since the test would leverage a writeable snapshot at the DR site. If they never wanted to test (highly unlikely), then I'm assuming it would work without the SnapView license?

Slowrider, you are right about this. SnapView snapshot is need to be created on the secondary storage system for testing purpose. You can find more information on
MirrorView Adapter for VMware Site Recovery Manager Release Notes
Please read "Configuring the storage for Site Recovery Manager" part on page 12
During failover testing, the MirrorView Adapter uses SnapView snapshots. When you create a SnapView snapshot of a LUN for a virtual machine, the name of the snapshot must include the following text string: VMWARE_SRM_SNAP. During failover testing, the MirrorView Adapter looks for this text string in the name of the inactive snapshot(s) for the virtual machine LUN(s) and creates a consistent snap session for this snapshot(s). When failover testing is finished, the MirrorView Adapter stops the SnapView session automatically.

It is a little fresh, we will make some research and get back to you.

The SnapView is required for testing failove and testing failback as SRM needs the snapshots for test scenarios. But if you are not going to do test, I don't think you need the SnapView.

Slowrider, further explanation on difference between executing SRM recovery plan and testing the environment:

I have successfully run a test recovery using a CX4-120 at our recovery site with a VNX 5500 at our production site. Snapview seemed to do just what it needed to do for the test and everything went well. I was curious though and I cannot seem to find any documentation on this.... do I need to remove my snapshot after I do the test? or do I just use the same snapshot over and over for my testing? We will need to do quarterly test recovery so not sure if I need to do a snapshot each time or just the one for each lun once... Any thoughts?
Thanks
Toby
