Location Codes
The 2105 Model Exx/Fxx and Expansion Enclosure storage facility uses Physical Location Codes or AIX
Location Codes to provide mapping of the failing field replaceable units. The location codes are produced
by the system unit's firmware and AIX.
For quick access to the FRU location diagrams, find the FRU in the chapter table of contents on page ,
and go to the indicated page.
For a list of which FRU location codes are available in this chapter, see the chapter table of contents on
page .
AIX Location Codes
The basic formats of the AIX location codes are:
v For non-SCSI devices/drives
AB-CD-EF-GH
v For 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
v The AB value identifies a bus type or PCI parent bus as assigned by the firmware.
v The 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.
v The EF value identifies a connector.
v The 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
