Address Mapping The bridge supports three addressing methods for mapping SCSI targets to Fibre Channel initiators (hosts): ■ Indexed Addressing - Allows editing and maintenance of a static address mapping table. ■ Auto Addressing (default setting) - Automatically creates a new address mapping table every time the bridge is power cycled. ■ SCC Addressing - Implements the SCSI-3 controller commands SCSI storage array addressing to address SCSI devices attached to the bridge. SCSI targets are selected by mapping the appropriate values into the FCP LUN field, and correlating a Fibre Channel LUN value to a SCSI bus:target:LUN value. The bridge acts as a single initiator on each SCSI bus, defaulting to ID 7. All commands passed through to a SCSI bus originate from this SCSI ID. Note The SCSI bus number corresponds to the physical SCSI ports on the back of the bridge. For example, SCSI bus 0 corresponds to SCSI port 0 on the back of the bridge. On the FC 2/1 LV, two ports are utilized per bus (which allows external terminations or installations in the middle of a bus). 40 Address Mapping Chapter 2
