IBM SA38-0512-03 manual AIX Location Codes, Ab-Cd-Ef-G,H

AIX Location Codes

The basic formats of the AIX location codes are:

ŸFor non-SCSI devices/drives AB-CD-EF-GH

ŸFor SCSI devices/drives

AB-CD-EF-G,H

For planars, cards, and non-SCSI devices the location code is defined as:

AB-CD-EF-GH

Device/FRU/Port ID

Connector ID

devfunc Number, Adapter Number or Physical Location Bus Type or PCI Parent Bus

ŸThe AB value identifies a bus type or PCI parent bus as assigned by the firmware.

ŸThe CD value identifies adapter number, adapter's devfunc number, or physical

location. The		devfunc number	is defined as the PCI device number times 8, plus
the	function	number.
Ÿ The	EF value	identifies a	connector.

ŸThe GH value identifies a port, address, device, or FRU.

Adapters and cards are identified with just AB-CD.

The possible values for AB are:

00

Processor

bus

01

ISA

bus

02

EISA

bus

03

MCA bus

04

PCI

used in

the

case

where

the

PCI

bus cannot

be identified

05

PCMCIA

buses

xy

For

PCI

adapters

where x

is

equal

to

or

greater than 1. The x and

y are characters in the

range

of

0-9, A-H,

J-N, P-Z (O,

I,

and

lower

case are

omitted) and are

equal to the parent

bus's

Property.

The possible values for CD depend on the adapter/card.

For pluggable PCI adapters/cards, CD is the device's devfunc number (PCI device number times 8, plus the function number). The C and D are characters in the range
