AIX Location Codes
The basic formats of the AIX location codes are:
ŸFor
ŸFor SCSI devices/drives
AB-CD-EF-G,H
For planars, cards, and
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

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
