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
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,
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
CD
depend
on
the
adapter/card.
For
pluggable
PCI
adapters/cards,
CD
is
the
device’s
devfunc
number
(PCI
device
number
times
8,
plus
the
function
number).
The
C
and
D
are
characters
in
the
range
of
0-9,
and
A-F
(hex
numbers).
The
location
codes
therefore
uniquely
identify
multiple
adapters
on
individual
PCI
cards.
EF
is
the
connector
ID,
used
to
identify
the
adapter’s
connector
to
which
a
resource
is
attached.
GH
is
used
to
identify
a
port,
device,
or
FRU.
For
example:
v
For
async
devices,
GH
defines
the
port
on
the
fanout
box.
The
values
are
00
to
15.
v
For
a
diskette
drive,
H
identifies
either
diskette
drive
1
or
2.
G
is
always
0.
v
For
all
other
devices,
GH
is
equal
to
00.
For
integrated
adapter,
EF-GH
is
the
same
as
the
definition
for
a
pluggable
adapter.
For
example,
the
location
code
for
a
diskette
drive
is
01-D1-00-00.
A
second
diskette
drive
is
01-D1-00-01.
