iSCSI host LUN access is determined by the specific iSCSI target to which the

host connects. Pay special attention to the VPG index portion of the IQN string; it

is critical to understanding which group of storage array LUNs the host will

access.

In Figure 4-15, the iSCSI host has logged into iSCSI target for VPG0. The host

can access VPG0 LUNs 1 and 2 from the storage array.
