Indexed Addressing Method
Indexed addressing allows for host bus adapter (HBA) drivers that use only
Peripheral Device Addressing to access SCSI devices attached to the router. This
addressing is done by use of a table, which is indexed by sequential LUN values,
indicating the selected BUS:TARGET:LUN devices. In this mode, it is not
possible to address the router as a controller unit directly.
The maximum size of the table is equal to the number of buses multiplied by the
number of targets per bus less one Initiator ID per bus, multiplied by the number
of LUNs per target. The index table can be manually edited. A method is also
provided to perform SCSI device discovery and fill the index table.
See Table 30 for the Indexed addressing table.
