And dont call it Cellera or it wont work till you trade one l or an r ☺

The white paper you're looking for is called "Domain Management with EMC Unisphere for VNX".  It details the specifics around what you need - a multi-domain setup which would allow your VNX and Celerra to be in the same UI interface.

Essentially the steps are:

1) login to the VNX domain as administrator

2) establish a multi-domain cnonection from the VNX to the Celerra

3) create user accounts in both domains with the same credentials

Note that VNX gateways make things a little more interesting and you have to jump through a few hoops with the right versions of Unisphere required.

Let us know if that helps!

can i call it Clarrion ?
