1. If the system has logical partitions, perform this procedure from the logical partition that reported the
problem. To determine if the system has logical partitions, go to Determine if the system has logical
partitions before continuing with this procedure.
2. Were you performing an IPL from removable media (IPL type D) when the error occurred?
v No: Continue with the next step.
v Yes: Exchange the FRUs in the failing item list for the reference code that sent you to this
procedure.
This ends the procedure.
3. Look in the service action log (see "Use the service action log" on page 7) for other errors logged at
or around the same time as the 310x SRC. If no entries appear in the service action log, use the
product activity log (see "Use the product activity log" on page 9). Use the other SRCs to correct the
problem (see the System reference codes topic) before performing an IPL. Contact your next level of
support as necessary for assistance with SCSI bus problem isolation. If the problem is not corrected,
continue with the next step.
4. Perform an IPL to DST (see Performing an IPL to DST in the iSeries
information). Does an SRC appear on the control panel?
v No: Continue with the next step.
v Yes: Go to step 6 (See page 190).
5. Does one of the following displays appear on the console?
v Disk Configuration Error Report
v Disk Configuration Attention Report
v Disk Configuration Warning Report
v Display Unknown Mirrored Load-Source Status
v Display Load-Source Failure
– Yes: Are all of the reference codes 0000? On some of the displays, you must press F11 to
display reference codes.
- No: Continue with the next step. Use the reference code that is not 0000.
- Yes: Go to "LIC-PIP11" on page 123 and use cause code 0002.
This ends the procedure.
– No: Look at the product activity log (see "Use the product activity log" on page 9 for details).
Is an SRC logged as a result of this IPL?
– Yes: Continue with the next step.
– No: You cannot continue isolating the problem. Use the original SRC and exchange the failing
items, starting with the highest probable cause of failure (see the failing item list for this
reference code in the System reference codes) topic. If the failing item list contains FI codes,
see the "Failing items" on page 249 topic to help determine part numbers and location in the
system.
This ends the procedure.
6. Is the SRC the same one that sent you to this procedure?
v Yes: Continue with the next step.
v No: Record the SRC on the Problem summary form. Then, go to the System reference codes topic
to correct the problem.
This ends the procedure.
7. Perform the following:
