Specifications

The period (·) identifies sublocations (DIMMs on a memory riser card, SCSI addresses,
cables). The following are examples:
v P1-M1.4 identifies DIMM 4 on memory riser card 1 plugged into planar P1.
v P1-C1.1 identifies processor 1 on processor card 1 plugged into planar P1.
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 as described in
Chapter 5, “Error Code to FRU Index” on page 99, 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 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 Typing 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.
