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 Processor bus
01 ISA bus
02 EISA bus
03 MCA bus
04 PCI bus used in the case where the PCI bus cannot be identified
05 PCMCIA 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 lower case are omitted) and are equal to the parent
bus’s ’ibm, aix-location’ open firmware property.
The possible values for CD depend on the adapter/card:
