Addressing Methods and Table Structures

177Network Storage Router e1200-160

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 25 for the Indexed addressing table.
