Error Code Description
B1xx 4690 Description: Operating system surveillance time out (AIX to service processor interface failure).
Action:
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, another error points to the cause of the operating system crash.
Use the other error as the starting point for your service action.
If the system will not boot to AIX, power off and look at the service processor error log. Look for
error codes (with time stamps that correspond to the boot that was just attempted) that indicate
hardware failures. If these error codes are found, record them, find the error code listed in the
Chapter 5, "Error Code to FRU Index", on page 209, and perform the indicated actions.
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:
a. Look at the AIX error log entry containing B1xx4690. This is a "SCAN_ERROR_CHRP"
b. In the detail data, find the string "B1xx4690" (If present, it will be at byte 60 of the detail
c.
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.
B1xx 4691 Description: System firmware to service processor interface failure. (System firmware surveillance
time out)
Action:
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.

an 8-character error code, go to the "Checkpoint and Error Code Index" on page 213. If no
location code is specified, and you have a 4-character checkpoint (for example, Exxx), go to
"Firmware Checkpoints" on page 168.
3. If your checkpoint is 91FF, perform the following:
a. Replace the RIO cable attached to RIO-2 port 0 (U0.1-P1/Qx) of the base system.
b. Replace the RIO adapter card of the I/O subsystem attached to the other end of the RIO
c. Replace the CEC backplane, location U0.1-P1.
4. If the problem is not resolved, call service support.
