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 345, 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 books 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).
You can determine the FRU part numbers of the electronic assemblies in a partition by using the
lscfg -vp
| pg
command on the AIX command line to display the detailed VPD of all assemblies. Notice that the
FRU part number information for processors and memory books may be at the bottom of the command
output.
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
Rack identify LED
v
Processor subsystem drawer identify LED
v
I/O drawer identify LED
v
RIO port identify LED
v
FRU identify LED
– Power subsystem FRUs
– Processor subsystem FRUs
– I/O subsystem FRUs
v
I/O adapter identify LED
v
DASD identify LED
The identify LEDs are arranged hierarchically with the FRU identify LED at the bottom of the hierarchy,
followed by the corresponding processor subsystem or I/O drawer identify LED, and the corresponding
rack-identify LED to locate the failing FRU more easily.
Any identify LED in the system may be flashed (when the processor subsystem is in the failed state and
power is on) by using the service processor LED Control Menu contained in the System Information Menu
of the Privileged User Menus. For information about using the LED Control Menu, see page 730.
Any identify LED in the system can also be flashed by using the Identify and Attention Indicators task in
diagnostics. The procedure to use the Identify and Attention Indicators task in diagnostics is outlined in
RS/6000 and
Eserver
pSeries Diagnostic Information for Multiple Bus Systems
.
If the service processor menus and AIX diagnostics are not available, the FRU identify LEDs can be
flashed by one of the following procedures:
v
If the system is configured as a full partition, the system may be booted to the open firmware prompt
and the command
FRU-LED-MENU
entered. A menu displays that allows you to enable the desired
FRU identify LED. See “System Power Control Menu” on page 720 for instructions on setting up the
boot mode to enable the boot to the open firmware prompt.
v
If the system is logically partitioned, the HMC must be attached. You can use the HMC to enable any
FRU identify LED to be flashed. See the
IBM Hardware Management Console for pSeries Installation
and Operations Guide
for instructions on activating and deactivating a FRU identify LED.
