Your vRanger/VCB is phyiscal correct? What you need to do is remove the vRanger lun from the list of datastores in VC if you formatted it as VMFS already, unpresent it from the ESX hosts and present it to a physcial vRanger/VCB server.
In regards to presenting VMFS luns to the VCB box....... it's just like how you present an existing lun to a new ESX server. You make sure the lun ID's are the same etc.
LUNA is LUND ID 1 on ESX1, ESX 2 and VCB
LUNB is LUN ID 2 on ESX1, ESX2 and VCB
