RIOIP02

Use this procedure to determine the status of HSL/RIO ports in the loop and to identify failing resources.

RIOIP02 Section-1

Procedure

  1. Sign on to SST or DST (if you have not already done so).
  2. Select Start a service tool > Hardware service manager > Logical hardware resources > High-speed link (HSL) resources.
  3. Select Include non-reporting resources. Move the cursor to the HSL loop that you want to examine and select Display detail.
  4. 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.
  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 "failed" link. You will be directed to find the other "failed" link. Go to step 7.
  6. 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, but did not find a failed link. Return to the procedure that sent you here. This ends the procedure.
    • No, the display that appears shows the status of the HSL ports for the next I/O bridge resource on the loop. Go to step 5.
  7. Find the information for the first failing resource using the following steps:
    1. Record the information as the first failing resource on the link.
    2. Record the resource name, card type-model, and part number.
    3. Record the link status of each port. Record 'Internal' if the port is designated as internal.
    4. Select Cancel to return to the Work with High-speed link (HSL) resources display.
    5. For the loop with the failure, select Resources associated with loop.
    6. For the HSL I/O bridge with the resource name that you recorded, select Associated packaging resources.
    7. Record the frame ID for the first failing link.
    8. Select Display detail, and record the card position for the first failing resource.
  8. Find the information for the other (second) failing resource by following these steps:
    1. Record this information as the second failing resource on the link.
    2. Select Cancel > Cancel to return to the Logical hardware associated with HSL loops display.
    3. Move the cursor to the HSL I/O bridge with the name of the first failing resource, and select Display detail > Include non-reporting resources.
    4. Follow the failed port by doing one of the following:
      • If the leading port is failed, select Follow leading port.
      • If the trailing port is failed, select Follow trailing port.
    5. You have located the second failing resource on the link.
    6. Record the resource name, card type-model, and part number.
    7. Record the link status of each port for the second failing link. Record "Internal" if the port is designated as internal.
    8. Select Cancel to return to the Logical hardware associated with HSL loops display.
    9. Select Include non-reporting resources > Associated packaging resources for the HSL I/O bridge or Network Interface Controller (NIC) with the resource name that you recorded for the second failed resource.
    10. Record the frame ID (if present) and port for the second failing link.
    11. Select Display detail and record the card position for the second failing resource.
  9. Have you repeated steps 1 through 8 for a second time during this procedure?
    • Yes, return to the procedure that sent you here. This ends the procedure.
    • No, continue with the next step.
  10. Do the first failing link and the second failing link have the same frame ID?
    • Yes, return to the procedure that sent you here. This ends the procedure.
    • No, continue with the next step to determine if the HSL cable connectors between the first and second failing resources are properly seated and cleaned.
  11. Disconnect the cable at the frame ID, card position, and port that you recorded for the first failing resource.
  12. 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.
  13. 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.
  14. Disconnect the cable at the frame ID, card position, and port that you recorded for the second failing resource.
  15. 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.
  16. 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.
  17. Wait a maximum of one minute to allow the changes to be detected by LIC.
  18. Determine if the link has become "operational" by repeating steps 1 through 8 for a second time. There is no need to duplicate any information you have already recorded. Return to the procedure that sent you here, when you are directed to do so in steps 1 through 8. This ends the procedure.
