a. Sign on to SST or to DST if you have not already done so.
b. Select "Start a service tool".
c. Select "Hardware service manager".
d. Select "Logical Hardware Resources".
e. Select "System bus resources".
f. Search for the "System Bus" resource identified in the BBBB field of the
DSA by moving the cursor to each "System Bus" resource and selecting the
option "Display detail" until you locate the bus number that matches the
decimal bus number value that you recorded from the DSA. Record the
resource name of the bus for later use.
g. From the "Logical Hardware Resources on System Bus" display, select the
function "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 No
↓
Go to step 12 of this procedure.
9. Was there a multi-adapter bridge number identified in the Cc value of the
DSA?
No Yes
↓
Go to step 11 of this procedure.
10. From the "Logical Hardware Resources on System Bus" display, examine the
status of all the resources under the bus, looking for a "failed" resource. You
will have to select the option "Resources associated with IOP" for each IOP
under the bus, to examine the status of the IOAs. You are looking for "failed"
resources under the bus. To determine the card position of a failed resource,
select option "Associated packaging resource(s)," then select the option "Display
detail" and record the frame ID, card position and part number. Return to the
procedure that sent you here.
This ends the procedure.
11. Search for the multi-adapter bridge number that is identified in the DSA by
moving the cursor to each "Mulit-adapter Bridge" resource and selecting the
"Display detail" option. 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.
12. 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. You will have to select the option "Resources associated with IOP" for
each IOP under the multi-adapter bridge, to examine the status of the IOAs.
You are looking for "failed" resources under the multi-adapter bridge and the
IOPs. To determine the card position of a failed resource, select the option
"Associated packaging resource(s)". Then select the option "Display detail" and
record the frame ID, card position and part number.
Did you find any failed resources?
No Yes
