Note: On some of these displays, you must press F11 to display reference codes. The characters
under Type are the same as the 4 leftmost characters of word 1. The characters under Reference
Code are the same as the 4 rightmost characters of word 1.
– No: Look at the Product Activity Log. See "Use the product activity log" on page 9 for details. Is
a reference code logged as a result of this IPL?
- No: Continue with the next step.
- Yes: Go to step 14 (See page 194).
– Yes: Go to step 14 (See page 194).
13. You are here because the IPL completed successfully. The last device you disconnected is the failing
item.
Is the failing item a disk unit?
v No: Exchange the failing item and reconnect the devices you disconnected previously. See the
Remove and replace procedures.
This ends the procedure.
v Yes: Exchange the failing FRU. Before exchanging a disk drive, you should attempt to save
customer data. Go to Start disk service here before exchanging a disk unit.
This ends the procedure.
14. Is the SRC or reference code the same one that sent you to this procedure?
v Yes: Continue with the next step.
v No: Record the SRC or reference code on the Problem summary form. Then, go to step 16 (See
page 194).
15. The last device you disconnected is not failing.
Have you disconnected all the devices that are identified by FI codes FI01105, FI01106, or FI01107 in
the FRU list?
v Yes: Replace the device backplane or backplanes associated with the devices you removed in the
earlier steps. If the device backplane does not fix the problem, then 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 System reference
codes. If the failing item list contains FI codes, see "Failing items" on page 249 to help determine
part numbers and location in the system.
This ends the procedure.
v No: Leave the device disconnected and return to step 9 (See page 193) to continue isolating the
possible failing items.
16. Is the SRC B1xx 4504, and have you disconnected the load-source disk unit? (The load-source disk
unit is disconnected by disconnecting disk unit 1.)
v No: Does one of the following displays appear on the console, and are all reference codes 0000?
– Disk Configuration Error Report
– Disk Configuration Attention Report
– Disk Configuration Warning Report
– Display Unknown Mirrored Load-Source Status
– Display Load-Source Failure
Note: On some of these displays, you must press F11 to display reference codes. The
characters under Type are the same as the 4 leftmost characters of word 1. The characters
under Reference Code are the same as the 4 rightmost characters of word 1.
- Yes: Continue with the next step.
- No: A new SRC or reference code occurred. Go to System reference codes to correct the
problem.
This ends the procedure.
v Yes: Continue with the next step.
