Location
Codes
Note:
When
the
system
is
running
under
the
Linux
operating
system
no
Linux
location
codes
exist,
but
physical
location
codes
might
display
in
the
Linux
error
logs.
This
system
unit
uses
physical
location
codes
in
conjunction
with
AIX
location
codes
to
provide
mapping
of
the
failing
field
replaceable
units.
The
location
codes
are
produced
by
the
system
unit’s
firmware
and
AIX.
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
location
code
is
an
alphanumeric
string
of
variable
length,
consisting
of
a
series
of
location
identifiers,
separated
by
a
dash
(-),
or
slash
(/),
or
a
pound
sign
(#)
character.
The
series
is
hierarchical;
that
is,
each
location
identifier
in
the
string
is
a
physical
or
logical
child
of
the
one
preceding
it.
v
The
-
(dash)
separator
character
represents
a
normal
structural
relationship
where
the
child
is
a
separate
physical
package
and
it
plugs
into
(or
is
connected
to)
the
parent.
For
example,
P1-M1
is
a
memory
DIMM
(M1)
plugged
into
a
system
backplane
(P1).
v
The
/
(slash)
separator
character
separates
the
base
location
code
of
a
function
from
any
extended
location
information.
A
group
of
logical
devices
can
have
the
same
base
location
code
because
they
are
all
on
the
same
physical
package,
but
may
require
extended
location
information
to
describe
the
connectors
they
support.
For
example,
P1-X1/S1
describes
the
location
of
the
serial
port
1
controller
and
its
connector
(S1),
which
is
located
on
the
system
backplane
P1
(its
base
location
code),
but
the
/
indicates
that
further
devices
can
be
connected
to
it
at
the
external
S1
serial
connector.
The
keyboard
controller
and
its
connector
likewise
have
location
code
P1-X1/K1,
which
means
they
have
the
same
base
location
code
(P1-X1)
as
serial
port
1,
but
a
different
external
connector.
In
contrast,
the
location
code
P1-X1/K1-K1
actually
points
to
the
device
connected
to
connector
K1;
that
is,
the
keyboard.
The
following
are
examples:
v
U0.1-P1-M1
identifies
memory
DIMM
M1
plugged
into
the
system
backplane
P1.
v
U0.1-P1-X1/S1
identifies
serial
port
1
controller
on
a
service
processor
card
X1,
plugged
into
the
system
backplane
P1,
or
the
connector
for
serial
port
1.
v
U0.1-P1-X1/K1-K1
identifies
a
keyboard
K1,
attached
to
connector
K1
on
the
service
processor
card
X1
plugged
into
system
backplane
P1.
AIX
Location
Codes
Note:
When
the
system
is
running
under
the
Linux
operating
system,
AIX
location
codes
are
not
available.
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
