of 0-9, and A-F (hex numbers). This allows the location code to uniquely identify multiple adapters on individual PCI cards.

For pluggable ISA adapters, CD is equal to the order the ISA cards defined/configured either by SMIT or the ISA Adapter Configuration Service Aid.

For integrated ISA adapters, CD

is equal to a unique

code identifying the ISA

adapter. In most cases this is

equal

to the adapter's physical location code.

where

a

physical

location code

is not

available, CD is be FF.

EF

is

the

connector

ID. It is

used to

identify the

adapter's connector that a

is

attached to.

 

 

 

 

GH is used to identify a port, device, or FRU. For example:

Ÿ For async devices GH defines the port on the fanout box. The values are 00 15.

Ÿ For a diskette drive H defines which diskette drive 1 or 2. G is always

Ÿ For all other devices GH is equal to 00.

For

integrated adapter, EF-GH

is the same as the definition for a

pluggable ada

For

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

second

diskette

drive is 01-D1-00-01.

 

 

For

SCSI

the location code 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 vali

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

There is also a bus location code that is generated as '00-XXXXXXXX' where XXXXXXXX is equivalent to the node's unit address.
