The best practice suggested to us by StorageTek/Sun is to have a zone for
each combination of host port and controller. I am told that this is due to
the controllers not being happy seeing the other controller.
So if you have a single HBA with a single port and two volume controllers,
you will need to have two zones: (HBA,VC1) and (HBA,VC2). Each host that is
connected would have two zones configured for it. If the host is dual
attached, then you would need 4 zones.
