Configuring Fibre Channel Array Hosts and LUN
Assignments
When configuring Fibre Channel array hosts, you must treat each iSR6200 virtual
port group (VPG) as its own unique Fibre Channel host within the virtualized
storage array. This means if you have only one VPG enabled, the iSR6200 will
have only one host entity. If you enable two more VPGs,
the iSR6200 presents
three separate host entities to your storage array.
Each host entity must contain WWPNs from the same VPG. Figure 4-8 shows a
correct configuration.

Do not simply group all Fibre Channel ports from the iSR6200 router into a single
host entity. Doing so defeats the purpose of virtual port groups, limiting you to 256
LUNs. It will also cause problems when you later try to restore access to
additional LUNS.
