4–ConfigurationControlling per-Host LUN Access on the iSR6200In Figure 4-17, the iSCSI host has logged into iSCSI targets for both VPG1 andVPG2. The host can access both VPG1 and VPG2 LUNs 3 and 4.iSR6200Blade 1FC1FC221:00:00:c0:dd:13:16:f821:01:00:c0:dd:13:16:f821:02:00:c0:dd:13:16:f821:00:00:c0:dd:13:16:f921:01:00:c0:dd:13:16:f921:02:00:c0:dd:13:16:f9SANiqn.2004-08.com:isr6200.0834e00019.r1.00.20030020c2075970iqn.2004-08.com:isr6200.0834e00019.r1.00.20030020c2075970iqn.2004-08.com:isr6200.0834e00019.r1.00.20030020c2075970LAN20:03:00:20:c2:07:59:70Host EntitiesHost Entity 021:00:00:c0:dd:13:16:f821:00:00:c0:dd:13:16:f9Host Entity 121:01:00:c0:dd:13:16:f821:01:00:c0:dd:13:16:f9Host Entity 221:02:00:c0:dd:13:16:f821:02:00:c0:dd:13:16:f9Storage ArrayLUN 1LUN 2LUN 3LUN 4iSCSI HostLUN 3 LUN 4Figure 4-17. iSCSI Host Logged into iSCSI Target for VPG1Controlling per-Host LUN Access on the iSR6200The iSR6200 allows multiple iSCSI initiators to connect to a single Fibre Channeltarget through a specific VPG. Controlling individual LUN access for each iSCSIhost requires LUN mapping devices connected through the iSR6200.NOTE:Before proceeding with this section, be sure you have read and understandthe previous sections of this chapter.Figure 4-18 shows that even after logging into the VPG0 iSCSI target, the hostcannot access data LUNs on the storage array. To allow the iSCSI host access toeach LUN, you must configure the iSR6200 using either SANsurfer RouterManager or the CLI.4-22 ISR651101-00 G
