The . (period) identifies sublocations (DIMMs on a memory card or SCSI addresses).
The following are examples:
v P1-M1.4 identifies memory DIMM 4 on memory card 1 plugged into planar P1.
v P1-C1.1 identifies processor 1 on processor card 1 plugged into planar P1.
v P2-Z1-A3.1 identifies a SCSI device with SCSI address of LUN 1 at SCSI ID 3
attached to SCSI bus 1, which is integrated on planar P2.
v P2.1 identifies a riser card plugged into planar P2.
AIX Location Codes
The basic formats of the AIX location codes are as follows:
v For non-SCSI devices/drives:
– AB-CD-EF-GH
v For SCSI devices/drives:
– AB-CD-EF-G,H
Non-SCSI Devices/Drives
For planars, cards, and non-SCSI devices, the location code is defined as follows:
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, the 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 only with AB-CD.
The possible values for AB are:
00
01
02
03
04
05
xy
The possible values for CD depend on the adapter/card:
12
Service Guide
Processor bus
ISA bus
EISA bus
MCA bus
PCI bus used in the case where the PCI bus cannot be identified
PCMCIA buses
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-location' open firmware property.
