v If an expansion tower was powered off during the service action, does the expansion tower power
on complete successfully?
v If any IOP or IOA card locations were powered off using concurrent maintenance during the service
action, do the slots power on successfully?
v If you exchanged a FRU that should appear as a resource or resources to the system, such as an
IOA, or I/O bridge, does the new FRU's resource appear in HSM as operational?
– Yes: Continue with the next step.
– No: Verify that you have followed the power off, remove and replace, and power-on procedures
correctly. When you are sure that you have followed the procedures correctly, then exchange
the next FRU in the list. If there are no more FRUs to exchange, then contact your next level of
support.
5. Does the system/logical partition have mirrored protection? If you are not sure, select Yes.
v Yes: From the Dedicated Service Tools (DST) display, select Work with disk units, and resume
mirrored protection for all units that have a suspended status. See Work with Disk Unit Recovery in
the iSeries Service Functions
v No: Continue with the next step.
6. From the Start a Service Tool display, select Hardware service manager, and look for the I/O
processors that have a failed or missing status.
Are all I/O processor cards operational?
Note: Ignore any IOPs that are listed with a status of not connected.
v No: Display the logical hardware resource information for the non-operational I/O processors. For
all I/O processors and I/O adapters that are failing; record the bus number (BBBB), board (bb) and
card information (Cc). Continue with the next step.
v Yes: Go to step 10 (See page 102).
7. Perform the following:
a. Return to the Dedicated Service Tools (DST) display.
b. Display the Product Activity Log.
c. Select All logs and search for an entry with the same bus, board, and card address information
as the non-operational I/O processor. Do not include informational or statistical entries in your
search. Use only entries that occurred during the last IPL.
Did you find an entry for the SRC that sent you to this procedure?
v No: Continue with the next step.
v Yes: Ask your next level of support for assistance.
This ends the procedure.
8. Did you find a B600 6944 SRC that occurred during the last IPL?
v Yes: Continue with the next step.
v No: A different SRC is associated with the non-operational I/O processor. Go to the System
reference code list and look up the new SRC to correct the problem.
This ends the procedure.
9. Is there a B600 xxxx SRC that occurred during the last IPL other than the B600 6944 and
informational SRCs?
v Yes: Use the other B600 xxxx SRC to determine the problem. Go to the System reference code list
and look up the new SRC to correct the problem.
This ends the procedure.
v No: You connected an I/O processor in the wrong card position. Use the system configuration list
to compare the cards. When you have corrected the configuration, go to the start of this procedure
to verify the bus repair.
This ends the procedure.
10. Use the hardware service manager function to print the system configuration list.
