RHEV in a DR Setup with VNX5200's ?

Anybody tried to setup a Red Hat Enterprise Virtualization - RHEV in a DR configuration with two VNX5200's ?

Please share information on how to install RHEV in a DR configuration. As I understand you can only have one Master Storage Domain but  if you simply want to change the Master Storage Domain to any other Domain, simply put the current Maste into Maintenance mode.
