v No: The failing item was the multi-adapter bridge FRU 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.
This ends the procedure.
v Yes: Contact your next level of support.
This

Use this procedure to isolate a failing PCI I/O processor card from an SRC, when the system or logical
partition will not IPL.
Attention: The remove and replace procedure of all FRUs in this procedure must be performed using
″Dedicated Maintenance″.
1. Determine the ″PCI bridge set″ (multi-adapter bridge domain) by performing the following:
a. Record the bus number (BBBB), the multi-adapter bridge number (C) and the multi-adapter bridge
function number (c) from the Direct Select Address (DSA) in word 7 of the SRC in the SAL entry.
See “Breaking down the SRC” on page 63 for help in determining these values.
b. Use the bus number that you recorded and the ″System Configuration Listing″ or ask the
customer to determine what frame the bus is in.
c. Record the frame type where the bus is located.
d. The PCI bridge set is the group of card positions controlled by the same multi-adapter bridge on
the bus that you recorded. Use the ″System Configuration Listing″, the card position table for the
frame type that you recorded, the bus number, and the multi-adapter bridge number to determine
the PCI bridge set where the failure occurred. Refer to the “Card positions” on page 65 (located in
the Bus PIP Overview topic) to locate the card position table for the frame type that you recorded.
e. Print out the Installed features in a PCI bridge set form to use in the following steps.
f. Using the card position table, record the PCI bridge set card positions and multi-adapter bridge
function numbers in the form.
g. Examine the PCI bridge set in the frame, and record the information in the form for all of the
positions with IOP and IOA cards installed in them.
h. In the form, start at the top row and search down the ″IOP″ or ″IOA″ column (increasing
multi-adapter bridge function numbers) and mark each IOP with an ″X″ until you hit the bottom of
the column. The IOPs that you marked with ″X″ are all under the control of the multi-adapter
bridge indicated in the DSA.
2. Did the SRC appear on the system control panel or the system console? (This would happen if the
system does not have multiple partitions or if the failure occurred in the Primary partition of a system
with multiple partitions.)
v No: When this procedure instructs you to power off and power on the system or partition, power off
or power on only the partition that reported the problem by selecting Work with system partitions
under SST/DST. Then, from the Primary partition, use HSM concurrent maintenance to power off
the card positions that you are instructed to work with. The remove and replace procedures for
those positions will guide you through the HSM concurrent maintenance functions. This procedure
will guide you to the correct remove and replace procedure for each card position that you are
instructed to work with. Continue with the next step.
v Yes: This procedure instructs you to power off and power on the system or partition with the
problem. Perform that function as you would normally power off and power on the system.
Continue with the next step.
3. Power off the system or partition.
4. Remove all the IOPs you marked with an ″X″ and all the IOAs in the form. Be sure to record the card
position of each IOP and IOA so that you can reinstall it in the same position later. To determine the
