5–Performing Data MigrationPresenting LUNs to the Server for Online Data MigrationISR654608-00 B 5-5To present source and destination LUNs from iSCSI arrays:1. Determine the iSCSI initiator name of each blade by issuing the showiscsi command; see page 6-59.2. Using an array management utility, register the router as a host using theiSCSI qualified name (IQN) of the iSCSI port, and then assign LUNs to thishost.3. Using the CLI, discover iSCSI storage arrays by issuing the iscsidiscover command (see page 6-18).4. List the discovered iSCSI targets, as well any Fibre Channel targets (ifpresent), by issuing the show targets command (see page 6-85).5. Log into the iSCSI target by issuing the iscsi login command (seepage 6-19).After 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.NOTE:Some iSCSI arrays require pre-registered hosts for the iscsidiscover command to succeed. For these arrays, manually create ahost with the IQN of the router iSCSI port before you issue thecommand.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.
