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 AB-CD.

The possible values for AB are:

00Processor bus

01ISA bus

02EISA bus

03MCA bus

04PCI bus used in the case where the PCI bus cannot be identified

05PCMCIA 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 lowercase are omitted) and are equal to the parent bus's ibm, aix-loc Open Firmware Property.

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

ŸFor 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 of 0-9, and A-F

(hex numbers). Location codes therefore uniquely

identify

multiple adapters on

individual

PCI cards.

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