IBM RS/6000 manual AIX Location Codes, Ab-Cd-Ef-G,H

Each location identifier consists of one alpha prefix character that ide type, and a decimal integer number (typically one or two digits) that id cific instance of this location type. Certain location types may also supp ondary sub-locations, which are indicated by appending a period (".") ch sub-location instance number.

Specifically, the format of a location code is defined as follows:

pn[.n][- or /]pn[.n][- or /]...

Where	p is a		defined	alpha	location type prefix,			n is a location instan
[.n] is a sub-location instance					number (where applicable). Sub-location notation
used only		for	location types		which		have clearly defined and limited expa
for example, memory SIMMs slots					on	a	memory card. Primarily, the [.n] sub-loc
notation	is	intended for		use	as	an	abbreviation of	the location code in

1.Based on the device structure, the abbreviated sub-location code co same information in a more concise form than an additional level of loca

identifier -- for example:

ŸP1-M1.4 (pluggable module 4 on Memory Card 1 on Planar 1), rather th P1-M1-M4

ŸP1-C1.1 (pluggable CPU 1 on CPU Card 1 on Planar 1), rather than P1-C1-C1

ŸP2-Z1-A3.1 (LUN 1 at SCSI ID 3 on integrated SCSI bus 1 from Plana rather than P2-Z1-A3-A1

2.The sub-location is either a basic physical extension or sub-enclosure base location, but does not represent additional function or connectivity

example, a drawer in a rack (U1.2) or a riser card on an I/O boa

AIX Location Codes

The basic formats of the AIX location codes are:

ŸFor non-SCSI devices/drives AB-CD-EF-GH

ŸFor SCSI devices/drives

AB-CD-EF-G,H

For planars, cards, and non-SCSI devices the location code is defined as:
