c. If you were unable to resolve the problem by reloading the service
processor code, then follow the service actions for the SRC you
recorded in the previous step.
3. The system has now IPLed past the original error, but to prevent the error from
occurring again a successful IPL to DST must be completed.
Select an alternate IPL media with a KNOWN GOOD level of code. Change
the IPL mode to D using control panel function 2. IPL to DST using the
alternate IPL media.
4. Did the IPL to DST complete successfully?
Yes No
↓ Follow the service actions for the new SRC. Go to “Starting Point for
All Problems” on page 4.
5. The service processor problem has been resolved. If this failure occurs again,
the system may require a slip install of Licensed Internal Code.
SP-PIP43
This procedure is for IPL failures that terminate with SRC B1XX4609.
The failing item is a card, cable or card enclosure connected to bus 1 that might
cause an interface failure between the service processor and the IPL load-source
device.
1. Record all of the SRC data words and describe the operation that was being
attempted.
2. Power off the system from the control panel. Check the cables and connections
between the System Unit, the load source IOP and the load-source device.
Re-seat cables where possible. Power on the system.
Does the same SRC occur ?
Yes No
↓ Follow the service actions for the new SRC. Go to “Starting Point for
All Problems” on page 4.
3. Locate the Extended Reference Code in SRC data word 3. This is the first half
of the second data word in control panel function 12:
12
xxxxxxxxEEEExxxx
xxxxxxxxxxxxxxxx
Use the following list to get a detailed description of the error condition and a
recommended service action:
Value for EEEE and Description: Recommended Service Action:
2103: No valid load source device was
found.
The service processor encountered no other
errors while attempting to open the load
source. This may indicate that no IOAs were
found. Re-seat or replace the first storage
IOA.
2107: No load source device was found.
Replace the first storage IOA, or the load
source device unit or isolate a problem on
that device interface.
