IBM RS/6000 7025 manual Aix, FRU Name, Location Code, Central

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

instance numbe

[.n] is a sub-location instance

number

(where applicable). Sub-location notation is

used only

for

location types

which

have clearly defined and limited expansion si

for example, memory SIMMs slots on a

memory card. Primarily, the [.n] sub-location

notation

is

intended

for

use

as an

abbreviation

of

the

location

code

in cases

1. Based

on

the

device

structure,

the abbreviated sub-location

code

conveys th

same information in a more concise

form than an

additional

level

of

location

identifier

--

for

example:

ŸP1-M1.4 (pluggable DIMM 4 on Memory Card 1 on Planar 1), rather than 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 Planar 2), rather than P2-Z1-A3-A1

2. The	sub-location is			either a		basic physical extension or sub-enclosure of the
base location,			but	does	not	represent additional function or connectivity; for
example,		a drawer		in a	rack	(U1.2) or a riser card on an I/O planar (P2.
