Use HSM to examine the HSL Loop to find a failing I/O bridge resource.
RIOIP04 Section-1
Procedure
Sign on to SST or DST.
Select Start a service tool > Hardware service manager > Logical hardware
resources > High-speed link resources.
Select Include non-reporting resources.
Move the cursor to the HSL loop that you want to examine and select Display
detail. The display that appears shows the port status of the
Network Interface Controller (NIC) for the loop that you selected.
Record the resource name, type-model, and serial number,
if it has not been previously recorded.
Is the status of the Leading port to next resource operational?
Yes, select Follow Leading Port. Then continue
with the next step.
No, you have found the first half of a "failing" link. Choose from the
following options:
If this is your first time through steps 1 through 7, go to step 8.
If this is your second time through steps 1 through 7, go to step 9.
Record the HSL resource name, type-model, part number, and port.
Is the resource name the same name that you recorded
for the NIC in step 4?
Yes, you have followed the HSL links around the loop and back to the
NIC on the system. You did not find a failed link. Return to the procedure
that sent you here. This ends the procedure.
No, the display that appears is showing the status of the HSL ports
for the next I/O bridge resource on the loop. Go to step 5.
If the status of the Leading port to next resource has become "operational",
the problem has been corrected. Return to the procedure that sent you here. This
ends the procedure.
If the status is still not "operational", continue with the next step.
If the resource type (shown near the top of the screen, just below
the bus number) is an HSL I/O bridge, then perform RIOIP04 Section-2: Collect the resource information below.
Then continue with the next step.
Select Follow leading port to
move to the resource with the failed link on the trailing port. If that resource
is an HSL I/O bridge, then perform RIOIP04 Section-2: Collect the resource information below.
Then return to the procedure that sent you here. This ends the procedure.
RIOIP04 Section-2: Collect the resource information
About this task
Find the information for the failing HSL I/O bridge using the following
steps:
Procedure
Record the resource name, card type-model, part number, and port.
Select Cancel to return to the Work with
high-speed link (HSL) resources display.
Select Resources associated with loop for
the loop with the failure.
Select Associated packaging resources for
the HSL I/O bridge with the resource name that you recorded.
Record the frame ID.
Select Display detail and record the card
position.
RIOIP04 Section-3: Clean and properly seat the cables
About this task
Determine if the HSL cable connectors for this HSL I/O bridge are
properly seated and clean.
Procedure
Disconnect one of the cables at the frame ID/unit of the HSL I/O
bridge.
Is the connection an optical link?
Yes, clean the HSL cable connector and port using the tools and procedures
listed in symbolic FRU OPT_CLN. Then
continue with the next step.
No, wait at least 30 seconds, and then continue with the next step.
Reconnect the cable to the port.
Attention: For copper cables, you must fully connect
the cable and tighten the connector's screws within 30 seconds of
when the cable makes contact with the port. Otherwise, the link will
fail and you must disconnect and reconnect again. Also, if the connector
screws are not tightened, errors will occur on the link and it will
fail.
Disconnect the other cable at the frame ID/unit of the HSL I/O
Bridge.
Is the connection an optical link?
Yes, clean the HSL cable connector and port using the tools and procedures
listed in symbolic FRU OPT_CLN. Then
continue with the next step.
No, wait at least 30 seconds, and then continue with the next step.
Reconnect the cable to the port.
Attention: For copper cables, you must fully connect
the cable and tighten the connector's screws within 30 seconds of
when the cable makes contact with the port. Otherwise, the link will
fail and you must disconnect and reconnect again. Also, if the connector
screws are not tightened, errors will occur on the link and it will
fail.
Refresh the port status by doing the following:
Wait 1 minute.
Select Cancel > Refresh > Display detail for the failing resource.
Determine if the link has become "operational" by repeating
steps 1 through 7 of
the main procedure a second time.
