iSR6200 Intelligent Storage Router Installation Guide - QLogic

4–ConfigurationConfiguring Fibre Channel Array Hosts and LUN AssignmentsConfiguring Fibre Channel Array Hosts and LUNAssignmentsWhen configuring Fibre Channel array hosts, you must treat each iSR6200 virtualport group (VPG) as its own unique Fibre Channel host within the virtualizedstorage array. This means if you have only one VPG enabled, the iSR6200 willhave only one host entity. If you enable two more VPGs, the iSR6200 presentsthree separate host entities to your storage array.Each host entity must contain WWPNs from the same VPG. Figure 4-8 shows acorrect configuration.Figure 4-8. Correctly Configured Storage Array Using Virtual Port GroupsDo not simply group all Fibre Channel ports from the iSR6200 router into a singlehost entity. Doing so defeats the purpose of virtual port groups, limiting you to 256LUNs. It will also cause problems when you later try to restore access toadditional LUNS.4-12 ISR651101-00 G
