Bus Pip Iop-02, Isolate To Failing I/O Adapter Resource - IBM iSeries Series Hardware Problem Analysis And Isolation

1. Go to the SST/DST display in the partition which reported the problem. Use STRSST if OS/400 is
running, use function 21 if STRSST does not work, or IPL the partition to DST.
2. On the Start Service Tools Sign On display, type in a User ID with QSRV authority and Password.
3. Select Start a service tool —> Hardware service manager —> Logical hardware resources —>
System bus resources.
4. Page forward until you find the IOP that you want to reset. For help in identifying the IOP from the
Direct Select Address (DSA) in the SRC, see "Breaking down the SRC" on page 63.
5. Verify that the 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 you are working on.
6. Move the cursor to the IOP that you want to reset, and select I/O Debug —> Reset IOP —> IPL IOP.
This ends the procedure.
Bus PIP IOP-02, Isolate to failing I/O adapter resource: For use by authorized service providers.
Use this procedure to isolate a failing I/O adapter under an IOP. The procedure will iterate through each
IOA under the IOP, powering each one off, and then resetting the IOP. This process will be repeated until
the failing IOA is isolated.
1. If the system is not IPLed, will it IPL to DST?
v No: Perform "Bus PIP IOP-03" on page 92.
This ends the procedure.
v Yes : From the SAL display for the SRC, record the count. Continue with the next step.
2. Go to the SST/DST display in the partition which reported the problem. Use STRSST if OS/400 is
running, use function 21 if STRSST does not work, or IPL the partition to DST.
3. On the Start Service Tools Sign On display, type in a User ID with QSRV authority and Password.
4. Select Start a service tool—>Hardware service manager—>Logical hardware
resources—>System bus resources.
5. Is there a resource name logged in the SAL entry?
v No: Do you have a location for the I/O processor?
– No: Record word 7 (the Direct Select Address (DSA)) of the SRC from the SAL display. Then,
continue with the next step.
– Yes: Go to step 9 (See page 91).
v Yes: Go to step 11 (See page 91).
6. Return to the HSM System bus resources display.
7. Locate the I/O processor by performing the following:
a. Select Display detail.
b. Compare the DSA from word 7 with the bus, card, board information for the IOP.
Note: The card information on the HSM display is in decimal format. You must convert the
decimal card information in to hexadecimal format to match the DSA format.
