40 Address Mapping Chapter 2
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).
