5–Performing Data MigrationPresenting LUNs to the iSR62005-4 ISR654608-00 Bon page 2-3. Create and activate Zone 3 and Zone 4 such that each routerblade can access all ports on source array controllers A and B.2. Zone in destination array controller ports with iSR6200 Fibre Channel ports.Refer to the appropriate topology shown in “Data Migration Configuration”on page 2-3. Create and activate Zone 5 and Zone 6 such that each routerblade can access all ports on destination array controllers A and B.3. Present LUNs from both the source and destination array to the iSR6200 asfollows:a. Register the following router Fibre Channel WWPNs from the samevirtual port group (VPG) as a single “host entry” in the storage array:BL1–FC1–VPG1BL1–FC2–VPG1BL2–FC1–VPG1BL2–FC2–VPG1b. In the array management utility, set the VPG host type to Windows.c. Present the LUNs (associated with the server) to the router as thesame LUN ID (if possible) as presented to the server. If multipleservers are being migrated at the same time using the same iSR6200,and different LUNs are presented to the different server as the sameLUN ID, you must use a different host entry using a VPG for LUNs thatbelong to different servers. (For details, refer to the Data MigrationService for iSR6200 Planning Guide, “Appendix A ChecklistExamples,” Step 4.)4. (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.LUN Presentation from iSCSI ArraysThis section provides the procedures for presenting LUNs and discovering iSCSIstorage arrays for offline data migration.NOTE:The iSR6200 supports a maximum of four VPGs. To expose more than 255LUNs from any Fibre Channel storage array, you may enable additionalVPGs in the iSR6200 blades. To present up to 1,024 LUNs (4×256) from thesame array to the iSR6200, repeat the preceding steps for each VPG.
