Use this procedure to determine a card position when no
location is given for a PCI adapter FRU.
This procedure uses the Direct
Select Address given in the reference code because no location was
given for a PCI adapter FRU.
- Is the partition an AIX® partition
or a Linux partition, or is
a management console attached?
- No:
- Continue with the next step.
- Yes:
- Go to PCI bus isolation using AIX, Linux, or the management console to isolate a
PCI bus problem from an AIX partition,
a Linux partition, or a management
console.
- If you were sent to this procedure with a specific Direct
Select Address (DSA), then use it. Otherwise, use the DSA in the reference
code. See DSA translation to find the
DSA in the reference code and translate it into the BBBB Cc values
that you use in later steps of this procedure.
- Perform the following steps:
- Record the bus number value, BBBB, in the DSA and convert
it to decimal format.
- Search for the decimal bus number in HSM or the System
Configuration Listing to determine which frame or I/O unit contains
the failing item. From the HSM screen select Logical Hardware Resources
> System Bus resources. Move the cursor to a system bus object
and select Display Detail. Do this for each bus until you find
the bus on which you are working.
- Record the frame or unit type.
- Record the Cc value in the DSA. Is the Cc value greater
than 00?
- No: The multi-adapter bridge and the multi-adapter
function number are not identified. Record that the multi-adapter
bridge is not identified in the DSA. The card slot cannot be identified
using the DSA. Go to step 9.
- Yes: Continue with the next step.
- Is the right-most character of the Cc value 'F'?
- No: Continue with the next step.
- Yes: Only the multi-adapter bridge number
is identified. Record the multi-adapter bridge number (the leftmost
character of the Cc value) for later use. The card slot cannot be
identified using the DSA. Go to step 9.
- Are you working with a B7xx reference code?
- No: Go to step 8.
- Yes: Continue with the next step.
- Is SST/DST available?
- No: Continue with the next step.
- Yes: Go to step 13.
- Use the Card positions with
the BBBB and Cc values that you recorded to identify the card position.
Then return to the procedure, failing item, or symbolic FRU that sent
you here. This ends the procedure.
- Perform the following steps:
- Sign onto SST or DST if you have not already done so.
- Select Start a service tool > Hardware service manager
> Logical Hardware Resources > System bus resources.
- 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?
- No: Continue with the next step.
- Yes: Go to step 12.
- Was there a multi-adapter bridge number identified in the
Cc value of the DSA?
- Yes: Continue with the next step.
- 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 resources > Display detail and record the unit ID and
part number.
Return to the procedure that sent you here. This ends the
procedure.
- 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.
- 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.
- 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 resources > Display detail and record the unit ID 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 sent you
here. This ends the procedure.
- No: Use the System Configuration Listing
and Card positions 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 leftmost character of the Cc value, then Card positions will help you 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 (indicated by a value of '0' in the
leftmost character) then Card positions will
identify which card slots are controlled by the bus (BBBB) that is
identified in the DSA. Return to the procedure that sent you here. This
ends the procedure.
- Perform the following steps:
- 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".
- Sign on to SST or DST if you have not already done so.
- Select Start a Service Tool > Hardware Service Manager
> Logical Hardware Resources > System Bus Resources.
- Search for the "System Bus" resource identified in BBBB
of the DSA by moving the cursor to each system bus resource and selecting Display
detail. Do this 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. From the Logical
Hardware Resources on System Bus display, select Include non-reporting
resources.
- From the Logical Hardware Resources on System Bus display,
examine all of the IOP and IOA resources under the bus. Look for a
"System card" value that matches the decimal value of the Cc
that you converted to decimal in step 12. Perform the following steps
to display the "System card" value for each of the IOP and
IOA resources:
Note: Do not examine virtual IOP resources.
- To examine the IOP resources:
- Select Associated packaging resources > Display detail.
The "System card" value of the IOP will be shown on the display.
- If the "System card" value matches the decimal value of
the Cc, then you have located the failing resource. Record the unit
ID and part number, and then return to the procedure that sent you
here. Otherwise, continue to examine all the IOP and IOA resources
on the bus.
- To examine the IOA resources:
- Move the cursor to an IOP or a virtual IOP resource and select Resources
associated with IOP > Associated packaging resources > Display detail.
The "System card" value of the IOA will be shown on the display.
- If the "System card" value matches the decimal value of
the Cc, then you have located the failing resource. Record the unit
ID and part number, and then return to the procedure that sent you
here. Otherwise, continue to examine all the IOP and IOA resources
on the bus.
Have you examined all the IOP and IOA resources under the bus?- No: Repeat this step.
- Yes: Continue with the next step.
- Did you locate a resource with a "System card" value
that matches the decimal Cc value from step 13?
- Yes: Record the unit ID and part number
of the resource. Return to the procedure that sent you here. This
ends the procedure.
- No: You will not be able to locate the
card using DST. Go to step 8 to
locate the card.
