c. Repeat this step until you find the IOP with the same DSA.
8. Select Cancel, and then go to step 12 (See page 91).
9. Locate the I/O processor in HSM by performing the following for each IOP:
a. Select Associated packaging resource(s)—>Display detail.
b. Repeat until you find the IOP with the same location.
10. Select Cancel—>Cancel and go to step 12 (See page 91).
11. Page forward until you find the multi-adapter bridge and IOP where the problem exists. Verify that the
multi-adapter bridge and IOP are correct by matching the resource name(s) on the display with the
resource name(s) in the Service Action Log (SAL) for the problem that you are working on.
12. For the IOP that you are working on, select Resources associated with IOP (if the I/O adapters are
not already displayed).
13. If there is an IOA that is listed in any state other than "operational", then perform steps 14 (See page
91) through 17 (See page 91) , starting with the disabled IOA by moving the cursor to the disabled
IOA. Otherwise, move the cursor to the first IOA that is assigned to the IOP.
14. Select Associated packaging resource(s)—>Concurrent maintenance—>Power off domain.
Record the Frame ID and Location of the slot you are powering off. Did the domain power off
successfully?
v No: Choose from the following options:
– If only one IOA was listed as failing, power down the system and replace the IOA. Re-IPL the
system. If a different SRC occured, go to "Starting point for all problems" on page 2 and work
that SRC. If there was no SRC, go to Verify the repair.
– If there were multiple failed IOAs and concurrent maintenance did not work on one, then move
to the next failed IOA and repeat step 14 (See page 91) through 17 (See page 91).
– If concurrent maintenance does not work for multiple failed IOAs, this procedure will not be able
to identify a failing I/O adapter. Return to the procedure that sent you here.
v Yes: Perform "Bus PIP IOP-01, IOP reset" on page 89, and then return here and continue with the
next step.
15. Did the IOP reset and IPL successfully?
v No: This procedure will not be able to identify a failing I/O adapter. Return to the procedure that
sent you here.
This ends the procedure.
v Yes: Check for the same failure that sent you to this procedure. Check the system control panel,
the SAL for the partition that reported the problem, or the Work with partition status display for the
partition that reported the problem. In the SAL, the count will increase if the SRC occurred again.
Continue with the next step.
16. Did the same SRC occur after the IOP was reset and IPL'd?
v No: Go to step 18 (See page 92).
v Yes: Perform the following steps:
a. Go to the Hardware Service Manager display.
b. Go to Packaging Hardware Resources.
c. Power on the IOA by selecting Power on domain.
d. Reassign the IOA to the IOP.
e. Return to the HSL resource display, showing the IOP and associated resources.
f. Continue with the next step.
17. Is there any other IOA, assigned to the IOP, that you have not already powered off and on?
v No: Go to step 20 (See page 92).
