5-6 Understanding the Configuration

Auto Addressing Automatically creates a new address
mapping table every time the
FCR200 is power cycled.
SCC Addressing Implements the SCSI-3 Controller
Commands SCSI storage array
addressing to address SCSI devices
attached to the FCR200.
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 FCR200 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.
As an example, SCSI bus 0 corresponds to SCSI port 0 on the
rear of the FCR200. SCSI bus 1 corresponds to SCSI port 1.
Indexed Addressing
Indexed Addressing allows for generic Fibre Channel host
bus adapters to access SCSI devices attached to the FCR200.
This is done by use of a table which is indexed by sequential
FCP LUN values, indicating selected BUS:TARGET:LUN
devices.
