Where AB-CD-EF are the same as non-SCSI devices.
G defines the control unit address of the device. Values of 0 to 15 are valid.
H defines the logical unit address of the device. Values of 0 to 255 are valid.
A bus location code is also generated as '00-XXXXXXXX' where XXXXXXXX is equivalent to the node's
unit address.
Examples of physical location codes displayed by AIX are as follows:
v Memory DIMM 2 of on system backplane P1:
U0.1-P1-M2
Examples of AIX location codes displayed are as follows:
v Pluggable PCI adapters:
1Z-08
1c-08
1f-08
1n-08
1H-08
1V-08
v Device attached to SCSI controller:
10-60-00-4,0
Multiple FRU Callout Instructions
If an eight-digit error code appears in the operator panel display or in Chapter 5, "Error Code to FRU
Index," on page 131, a location code for a failing part may also be specified. If the location code includes
a blank space followed by a lowercase x followed by a number, this is an error code with multiple FRU
callouts. This error can typically happen with memory DIMMs or processors, and may involve mixed types
of parts. In this case, check the system's configuration for FRU part numbers to determine the appropriate
set of FRUs.
You can determine the FRU part numbers of the electronic assemblies in the entire system by using the
service processor menus. From the General User menu, select Read VPD Image from Last System Boot,
then enter 90 to display detailed Vital Product Data (VPD).
If the system is running AIX, you can determine the FRU part numbers of the electronic assemblies in a
partition by using the lscfg -vp | pg command. This command displays the detailed VPD of the electronic
assemblies in the system. Notice that the FRU part number information for processors and memory
DIMMs may be at the bottom of the command's output.
If the system is running Linux, you can determine the FRU part numbers of the electronic assemblies in a
partition by using the lscfg -vp | more command. This command displays the detailed VPD of the
electronic assemblies in the system.
FRU Identify LEDs
This system is configured with an arrangement of LEDs that help identify various components of the
system. These include but are not limited to:
v Power subsystem FRUs
v System unit FRUs
Any PCI card in slot 1
Any PCI card in slot 2
Any PCI card in slot 3
Any PCI card in slot 4
Any PCI card in slot 5
Any PCI card in slot 6
