The current version of EMC's Unisphere for the VNX does not allow for more than one storage array to be present in a single "management domain"-- meaning you cannot (today) manage multiple EMC arrays from a single Unisphere session. Bummer. While this has been promised for a future release, it's a known limitation today.

And generally speaking, it's not a major issue, but rather a temporary inconvenience.

However, having more than one array in the storage or management domain has traditionally been a requirement of EMC's SAN Copy and MirrorView array-based software solutions. And when migrating data from a prior generation EMC array (or even a non-EMC array) to the VNX, these tools (SAN Copy specifically) come in very handy

The good news is that there are documented workarounds to use SAN Copy and MirrorView on the VNX.
