5–Performing Data MigrationPresenting LUNs to the Server for Online Data MigrationISR654608-00 C 5-7After successful iSCSI login, the iSCSI target comes online.6. (Optional) To discover the newly-presented LUNs and form the new arrays,if required, follow these steps:a. In the left pane of SANsurfer iSCSI/FC Router Manager, click theRouter tab.b. Right-click the appropriate blade.c. On the shortcut menu, click Rescan.Presenting LUNs to the Server for Online DataMigrationFor online data migration, you need to create access to all LUNs associated withthe server or servers through the router, and you must eliminate direct accessfrom the server to the storage array.Follow these basic steps to present the LUNs from the iSR6200 to the server:Step 1: Present Source LUNs to the InitiatorStep 2: Create Presented TargetsStep 3: Zone in Presented Targets with Initiator PortsStep 1: Present Source LUNs to the InitiatorMap the initiators to the LUN and create presented targets (virtual ports)associated with the source array target ports and the VPG. (For more information,see “Presented Targets” on page 3-9”.QLogic recommends that you create the presented target on the same FibreChannel port of the iSR6200 on which the source array port is discovered.Typically, Fibre Channel zoning is set up such that one source array port isdiscovered through one Fibre Channel port (one or more VPGs) of the iSR6200. Ifthe same source array target port is discovered through multiple Fibre Channelports (on the same VPG) of the iSR6200, create only one presented target portacross both blades of the iSR6200.NOTE:If the iSCSI storage array supports it, you can establish multipleconnections per session using multiple GbE ports on the same routerblade and storage array.
