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.
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 159, 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, memory riser cards, 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.
For example, if the location code U1.1-P1-M1.1 x4 was displayed, this indicates memory quad A (four
DIMMs) on the first memory riser card was suspected.
You can determine the FRU part numbers of the electronic assemblies in the system in one of the
following ways:
v 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).
v Using the lscfg -vp | pg command on the AIX command line
Enter the following command: lscfg -vp | pg to display the detailed VPD of all assemblies. Notice that
the FRU part number information for processors and memory DIMMs may be at the bottom of the
command output.
