If the repair actions for an error code are ineffective, continue to work upward through this group of
error codes (which is forward in time from the earliest time stamp to the latest) until either the problem
is fixed, you reach the error code that was first reported, or you are at the top of the list.
Four-Character Checkpoints
Four-character checkpoints in the form 8xxx, 9xxx, Axxx, Bxxx, and Exxx are listed in “Firmware
Checkpoints” on page 317. If you have a four-character code that begins with any character other than 8,
9, A, B, or E, refer to the
RS/6000 and
Eserver
pSeries Diagnostic Information for Multiple Bus Systems .
Replacing the Media Subsystem Operator Panel
Licensed programs frequently rely on system information that is stored in the VPD module on the media
subsystem’s operator panel. If the MAPs indicate that the operator panel should be replaced, the
pluggable VPD module must be swapped. If the old module is defective, or cannot be recovered, contact
service support.
Replacing the Network Adapter
If a network adapter is replaced, the network administrator must be notified so that the client IP addresses
used by the server can be updated. In addition, the operating system configuration of the network
controller may need to be changed in order to enable system startup. Also check to ensure that any client
or server that accesses this system is updated.
Determining Location Code
If you have an error code in the form 2xxx xxxx or Exxx, and no location code associated with it, the
location code may possibly be found in the following places, depending on the state of the system:
v For systems with AIX installed, if the system will boot into AIX, the location code will be reported when
error log analysis is run under AIX diagnostics.
v
If the system will boot into the system management services (SMS) menus, the SMS error log will
contain the location code associated with the error code.
v
If the system halted when the error occurred, the error code and location can be found in the LCD
progress indicator log, which can be accessed using the service processor menus. See “System
Information Menu” on page 724, then select
Read Progress Indicator From Last System Boot . Find
the error code that directed you to this note in the list, and the location code is part of the entry in the
log.
Attention: To identify a FRU, these MAPs refer to FRU identify LEDs. For more Information about the
FRU identify LEDs see “FRU Identify LEDs” on page 54.
