Action/
Possible Failing FRU
1. This error code indicates that the operating
system terminated early (which usually
implies an operating system crash). This
error code may appear in the service
processor error log by itself. However, in the
AIX error log, there should be another error
which points to the cause of the operating
system crash. Use the other error as the
starting point for your service action.
2. The other possibility is that the operating
system was not found during a prior boot
attempt. To determine if this occurred, do
the following: Look at the AIX error log entry
containing B1xx4690. This will be a
"SCAN_ERROR_CHRP" error with an
identifier of BFEC0425. In the detail data,
find the string "B1xx4690" (If present, it will
be at byte 60 of the detail data.) Then go
forward 8 bytes after the "B1" to byte 68
and look at bytes 68 and 69. If the values of
bytes 68 and 69 are A2B0, this indicates
that the firmware was unable to find a
bootable device in the boot list that is set in
the SMS menus. If the system is up, the
boot list problem has been corrected and
the B1xx 4690 can be treated as an
informational message with no actions
required.
3. Call service support.
1. Check for system firmware updates.
2. Go to the service processor main menu and
select System Information Menu, then
select Read Progress Indicators From
Last System Boot. Begin your repair action
with the error code or checkpoint
immediately preceding B1xx 4691. If a
location code displays with the error code or
checkpoint, replace the part at that location.
If changing that part does not fix the
problem, or no location code is specified,
and you have an 8-character error code, go
to the "Checkpoints and Error Codes Index"
on page 394. If changing that part does not
fix the problem, or no location code is
specified, and you have a 4-character
checkpoint, go to "Firmware Checkpoints"
on page 363.
3. If the problem is not solved, call the second
level of support.
1. Check for system firmware updates.
