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 163, 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 FRU part
numbers to determine the appropriate set of FRUs.
For example, if the location code U1.1-P1-M1.1 x2 was displayed, this indicates
memory pair A (two DIMMs) on the first memory riser card was suspected.
You can determine the FRU part numbers of the electronic assemblies in the system in
two 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
Type 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.
