RIOIP04

Use HSM to examine the HSL Loop to find a failing I/O bridge resource.

RIOIP04 Section-1

Procedure

  1. Sign on to SST or DST.
  2. Select Start a service tool > Hardware service manager > Logical hardware resources > High-speed link resources.
  3. 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.
  4. Record the resource name, type-model, and serial number, if it has not been previously recorded.
  5. 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.
  6. Record the HSL resource name, type-model, part number, and port.
  7. 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.
  8. Follow the steps in RIOIP04 Section-3: Clean and properly seat the cables below.
  9. Choose from the following options:
    • 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.
  10. 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.
  11. 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

  1. Record the resource name, card type-model, part number, and port.
  2. Select Cancel to return to the Work with high-speed link (HSL) resources display.
  3. Select Resources associated with loop for the loop with the failure.
  4. Select Associated packaging resources for the HSL I/O bridge with the resource name that you recorded.
  5. Record the frame ID.
  6. Select Display detail and record the card position.
  7. Go to step 11 of Section-1.

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

  1. Disconnect one of the cables at the frame ID/unit of the HSL I/O bridge.
  2. 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.
  3. 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 contacts the port. Otherwise, the link fails and you must disconnect and reconnect again. Also, if the connector screws are not tightened, errors occur on the link and it fails.
  4. Disconnect the other cable at the frame ID/unit of the HSL I/O Bridge.
  5. 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.
  6. 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 contacts the port. Otherwise, the link fails and you must disconnect and reconnect again. Also, if the connector screws are not tightened, errors occur on the link and it fails.
  7. Refresh the port status by doing the following:
    1. Wait 1 minute.
    2. Select Cancel > Refresh > Display detail for the failing resource.
    3. Determine if the link has become operational by repeating steps 1 through 7 of the main procedure a second time.
