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:
vFor non-SCSI devices/drives
AB-CD-EF-GH
vFor 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, Ada ter Number or Physical Location
Bus Ty e or PCI Parent Bus
vThe AB value identifies a bus type or PCI parent bus as assigned by the firmware.
vThe 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.
vThe EF value identifies a connector.
vThe 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
Locations
2VOLUME 3, ESS Service Guide

02 EISA bus
03 MCA bus
04 PCI bus used in the case where the PCI bus cannot be identified
05 PCMCIA busses
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 IBM, aix-loc Open Firmware 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 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. In cases where a physical location code is not available,
CD will be FF.
EF is the connector ID. It is used to identify the adapter’s connector that a resource is attached to.
GH is used to identify a port, device, or FRU. For example:
vFor async devices GH defines the port on the fanout box. The values are 00 to 15.
vFor a diskette drive H defines which diskette drive 1 or 2. G is always 0.
vFor all other devices GH is equal to 00.
For integrated adapter, EF-GH is the same as the definition for a pluggable adapter. 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, Ada ter Number or Physical Location
Bus Ty e 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 valid.
H defines the logical unit address of the device. Values of 0 to 255 are valid.
There is also a bus location code that is generated as ’00-XXXXXXXX’where XXXXXXXX is equivalent to
the node’s unit address.
Examples of physical location codes displayed by AIX are:
vProcessor Card in slot 1 of planar 1
P1-C1
vMemory DIMM in system planar slot 2
Locations
2105 Model Exx/Fxx and Expansion Enclosure Locations, CHAPTER 7 3

P1-M2
vMemory DIMM 12 in card in slot 2 of system planar
U1-P1-M2.12
Examples of AIX location codes displayed are:
vIntegrated PCI adapter
10-80 Ethernet
10-60 Integrated SCSI Port 1
30-58 Integrated SCSI Port 2
vPluggable PCI adapters
20-58 to 20-5F Any PCI card in slot 1
20-60 to 20-67 Any PCI card in slot 2
10-68 to 10-6F Any PCI card in slot 3
10-70 to 10-77 Any PCI card in slot 4
10-78 to 10-7F Any PCI card in slot 5
30-60 to 30-67 Any PCI card in slot 6
30-68 to 30-6F Any PCI card in slot 7
30-70 to 30-77 Any PCI card in slot 8
30-78 to 30-7F Any PCI card in slot 9
