Harold, your UCSM boot policy should incldue 2 SAN boot targets with the WWPNs of your SAN front end ports. Ideally you would have 2 targets per vHBA.
Your service profile should also include 2 vHBAs; 1 on each fabric.
You would then present LUNs to your host just like any other server.
You do not need to add the additional LUNs to the boot policy, only the boot LUN has to be defined there.
