 For async devices, GH defines the port on the fanout box. The values are 00 to

15.

 For a diskette drive, H identifies either diskette drive 1 or 2. G is always 0.

 For all other devices, GH is equal to 00.

For integrated adapter, EF-GH is the same as the definition for a pluggable adapter.

For example, the location code for a diskette drive is 01-D1-00-00. A second

diskette drive is 01-D1-00-01.

SCSI devices/drives

The location code for SCSI devices and drives is defined as:

AB-CD-EF-G,H

| | |||

| | | | Logical Unit address of the SCSI Device

| | | Control Unit Address of the SCSI Device

| | Connector ID

| devfunc Number, Adapter Number or Physical Location

Bus Type or PCI Parent Bus

Where:

 AB-CD-EF are the same as non-SCSI devices.

 G defines the control unit address of the device. Values of 0 to 15 are valid.

 H defines the logical unit address of the device. Values of 0 to 255 are valid.

A bus location code is also generated as 00-XXXXXXXX, where XXXXXXXX is

equivalent to the node's unit address.
