Logical
and
Physical
Locations
The
system
uses
physical
location
codes
in
conjunction
with
AIX
location
codes
to
provide
mapping
of
the
failing
field
replaceable
units
(FRUs).
The
location
codes
are
produced
by
the
system
unit’s
firmware
and
the
AIX
operating
system.
Physical
Location
Codes
Physical
location
codes
provide
a
mapping
of
logical
functions
in
a
platform
(or
expansion
sites
for
logical
functions,
such
as
connectors
or
ports)
to
their
specific
locations
within
the
physical
structure
of
the
platform.
Location
Code
Format
The
format
for
the
location
code
is
a
string
of
alphanumeric
characters
separated
by
a
dash
(-),
slash
(/),
pound
sign
(#)
or
period
(.)
character.
The
base
location
is
all
of
the
information
preceding
the
slash
(/)
or
pound
sign
(#).
The
base
location
identifies
a
device
that
is
connected
to
or
plugged
into
the
parent.
Extended
location
information
follows
the
slash
(/).
Extended
location
information
identifies
a
device
that
is
part
of
the
parent,
a
connector,
or
a
cable.
Cable
information
follows
the
pound
sign
(#).
Cable
information
identifies
a
cable
that
is
connector
to
parent.
The
following
are
examples:
v
P1-C1
identifies
a
processor
card
C1
plugged
into
planar
P1.
v
P1-M1
identifies
a
memory
card
M1
plugged
into
planar
P1.
v
P1-K1
identifies
a
keyboard
attached
to
K1
on
planar
P1.
v
P1/S1
identifies
serial
port
1
controller
on
planar
P1,
the
connector
for
serial
port
1,
or
the
cable
attached
to
serial
port
1.
v
P1-I2/E3
identifies
an
Ethernet
controller
3
on
the
card
in
slot
2
(I2)
on
planar
P1,
the
connector
for
Ethernet
controller
3,
or
the
cable
attached
to
Ethernet
controller
3.
v
P1-I2#E3
identifies
the
cable
attached
to
Ethernet
controller
3
on
the
card
in
slot
2
(I2)
on
planar
P1.
The
period
(.)
identifies
sublocations
(DIMMs
on
a
memory
card,
SCSI
addresses,
cables).
The
following
are
examples:
v
P1-M1.4
identifies
DIMM
4
on
memory
card
1
plugged
into
planar
P1.
v
P1-C1.1
identifies
processor
1
plugged
into
processor
card
1
which
is
plugged
into
planar
P1.
v
U0.1-P1/Z1–A3
identifies
a
SCSI
device
with
SCSI
ID
3
attached
to
SCSI
bus
1
on
planar
1
in
the
primary
I/O
drawer.
v
P2-Z1-A3.1
identifies
a
SCSI
device
with
SCSI
address
of
LUN
1
at
SCSI
ID
3
attached
to
SCSI
bus
1
from
planar
2.
v
P1-I2#E3.2
identifies
the
second
in
a
series
of
cables
attached
to
Ethernet
controller
3
on
the
card
in
slot
2
(I2)
on
planar
P1.
Depending
on
the
AIX
and
firmware
levels,
AIX
diagnostics
may
include
the
extended
location
information
when
identifying
a
planar
or
card.
The
extended
location
information
or
cable
information
is
always
included
when
identifying
a
cable
or
connector.
Location
codes
with
extended
location
information
that
are
displayed
without
a
description
identifying
the
devices
always
identify
the
cable
attached
to
the
port.
