392 Implementing the IBM Storwize V7000 with IBM Spectrum Virtualize V8.2.1
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.
 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.
 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.
6. If the previous preparation steps were followed, the Storwize V7000 is now seen as a host 
from the system to be migrated. LUs can then be mapped to the Storwize V7000. Map the 
external storage system by following the instructions that are shown in Figure 9-6.
