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
