When a LUN is added to a storage group for masking purposes, it is given a default HLU value, different from the LUN value (ALU), that is visible to the host. The default HLU value can be changed to a user-defined value. HLU corresponds to the LUN address you see on the host. ALU is the LUN number you see in Navisphere.
