SRC formats. Verify that the multi-adapter bridge is the correct one by matching the resource name
on the display with the resource name in the Service Action Log (SAL) for the problem that you are
working on.
5. Select Include non-reporting resources.
6. Move the cursor to the first IOP under the multi-adapter bridge.
7. For each IOP that is under the multi-adapter bridge that you are working on, select Associated
packaging resource(s) —> Display detail.
8. Record the location of the I/O processor (IOP).
9. Select Cancel —> Cancel.
10. Select Resources associated with IOP.
11. For each I/O adapter under the IOP, perform the following:
a. Select Associated packaging resource(s) —> Display detail.
b. Record the location.
12.
Power off the frame or tower. See Power on/off the system and logical partitions.
13. Remove one of the IOPs and all of its IOAs.
14. Power on the frame or tower. See Power on/off the system and logical partitions.
15. Check for the same failure which brought you to this procedure. Check the system control panel, the
Service Action Log (SAL) for the partition which reported the problem, or the Work with partition
status display for the partition that reported the problem.
16. Did the same SRC appear after the frame or tower was powered on?
v Yes: Power on the frame or tower. Then, continue with the next step.
v No: Go to step 19 (See page 96).
17.
Return to the System bus resources display showing the multi-adapter bridge and the associated
resources.
18. Is there another IOP under the multi-adapter bridge?
v No: Go to step 21 (See page 96).
v Yes: Go to step 12 (See page 96).
19. The failing IOP is located. The failing item is either the I/O processor or one of the I/O adapters that it
controls. Reinstall the IOP and I/O adapters that you just removed. Perform “Bus PIP IOP-02, Isolate
to failing I/O adapter resource” on page 90. If Bus PIP IOP-02 does not identify a failing I/O Adapter
then return here and continue with the next step in this procedure.
20. Exchange the I/O Processor that you identified in step 19 (See page 96).
Power on the frame or tower.
Does the same SRC that sent you to this procedure occur?
v No: The failing item was the IOP that you just exchanged. Reinstall all of the other IOPs and I/O
adapters that you removed during this procedure. Go to “Bus PIP verify - RA” on page 101.
v Yes: The failing item is the FRU containing the multi-adapter bridge which controls this IOP. Go to
step 22 (See page 96).
21. No failing IOPs. The failing item is the FRU containing the multi-adapter bridge which controls this
IOP.
22. Power off the system unit or I/O tower that you are working in.
23. Exchange the FRU containing the multi-adapter bridge using the symbolic FRU “MA_BRDG” on page
363.
24. Power on the system unit or I/O tower that you are working in.
Does the same SRC that sent you to this procedure occur?
