text: This system requires single-initiator zoning for all large configurations that contain 
  more than 64 host objects. Each server Fibre Channel port must be in its own zone, 
  which contains the Fibre Channel port and this system’s ports. In configurations of 
  fewer than 64 hosts, you can have up to 40 Fibre Channel ports in a host zone if the 
  zone contains similar HBAs and operating systems. 
  
  (cid:129) Storage system zones 
  
  In a storage system zone, this system’s nodes identify the storage systems. 
  Generally, create one zone for each storage system. Host systems cannot operate 
  on the storage systems directly. All data transfer occurs through this system’s 
  nodes. 
  
  (cid:129) Host zones 
  
  In the host zone, the host systems can identify and address this system’s nodes. 
  You can have more than one host zone and more than one storage system zone. 
  Create one host zone for each host Fibre Channel port. 
  
  – Because the Storwize V7000 should now be seen as a host from the external system 
  to be migrated, you must define the Storwize V7000 as a host or host group by using 
  the WWPNs or IQNs on the system to be migrated. Some legacy systems do not 
  permit LUN-to-host mapping and would then present all the LUs to the Storwize 
  V7000. In that case, all the LUs should be migrated.
