6.1.3 Fibre Channel Interface Addressing
One Fibre Channel port is assigned a target ID by addressing port ID. The AMS200 can address
up to 256 logical unit numbers for one port. Host computer accesses to the logical unit with
the required logical unit number by identifying the port of disk array subsystem using target
ID. The following figure illustrates fibre channel port addressing and logical unit number
assignment.
