a. Sign onto SST or to DST if you have not already done so.
b. Select Start a service tool—>Hardware service manager—>Logical Hardware
Resources—>System bus resources.
c. Put the bus number in the System bus(es) to work with field. Then, select Include non-reporting
resources, and examine the display.
Is there more than one multi-adapter bridge connected to the bus resource you are working with?
Yes: Continue with the next step.
v
v No: Go to step 11 (See page 100).
9. Was there a multi-adapter bridge number identified in the Cc value of the DSA?
Yes: Continue with the next step.
v
v No: From the Logical Hardware Resources on System Bus display, examine the status of all the
resources under the bus, looking for a "failed" resource.
– To examine the status of the IOAs, select Resources associated with IOP for each IOP under
the bus.
– To determine the card position of a failed resource, select Associated packaging
resource(s)—>Display detail and record the frame ID, card position, and part number.
Return to the procedure that sent you here.
This ends the procedure.
10. Search for the multi-adapter bridge number that is identified in the DSA by moving the cursor to each
Multi-adapter Bridge resource and selecting Display detail. Convert the System card value to
hexadecimal (it is displayed in decimal format). The hexadecimal System card value is the Cc
address of the multi-adapter bridge. When you find the multi-adapter bridge resource, where the
multi-adapter bridge number (the leftmost character of the hexadecimal Cc value) matches the
multi-adapter bridge number that you recorded from the DSA, then you have located the multi-adapter
bridge identified in the DSA.
11. From the Logical Hardware Resources on System Bus display, examine the status of all the
resources under the multi-adapter bridge, looking for a "failed" resource.
v To examine the status of the IOAs, select Resources associated with IOP for each IOP under
the multi-adapter bridge.
To determine the card position of a failed resource, select Associated packaging
v
resource(s)—>Display detail and record the frame ID, card position, and part number.
Did you find any failed resources?
Yes: One of the failing resources that you located is the problem. Return to the procedure that
v
sent you here.
This ends the procedure.
v No: Use the System Configuration Listing and the "Card positions" on page 65 (located in the Bus
PIP Overview topic) for the frame type that you recorded, to determine which card positions may
have the "failing" card. If you recorded that the multi-adapter bridge was identified in the Cc (the
leftmost character of the Cc value), then the "Card positions" on page 65 will identify which card
slots (PCI Bridge set) are controlled by the multi-adapter bridge that is identified in the Cc value. If
the multi-adapter bridge was not identified in the Cc value (the leftmost character is '0') then the
"Card positions" on page 65 will identify which cards slots are controlled by the buss (BBBB value)
that is identified in the DSA. Return to the procedure that sent you here.
This ends the procedure.
12. Perform the following:
a. Convert the hexadecimal Cc value in the DSA into a decimal value. You will be searching for the
decimal value in HSM where it will be called "System card".
b. Sign on to SST or to DST if you have not already done so.
c. Select Start a Service Tool—>Hardware Service Manager—>Logical Hardware
Resources—>System Bus Resources.
