This MAP calls for SRCs that require special repair actions to be completed by the service representative or the next level of support.

MAP4968 Section-1

Procedure

  1. Does the FRU list, in the serviceable event, that sent you here contain a symbolic FRU similar to Invalid-MTMS-cpssebay**?
  2. When the FRU list contains a symbolic FRU similar to Invalid-MTMS-cpssebay** the location code is invalid and cannot be used to determine the failing I/O enclosure.
  3. To determine the cpssebay** value from the symbolic FRU of Invalid-MTMS-cpssebay**, use the first column of Table 1.
    Table 1. Symbolic FRU location to type-location translation
    Symbolic FRU location code Location Type-location I/O enclosure number
    cpssebay00 1B1 1400-1B1 0
    cpssebay01 1B2 1400-1B2 1
    cpssebay02 1B3 1400-1B3 2
    cpssebay03 1B4 1400-1B4 3
    cpssebay04 2B1 1400-2B1 4
    cpssebay05 2B2 1400-2B2 5
    cpssebay06 2B3 1400-2B3 6
    cpssebay07 2B4 1400-2B4 7
  4. Determine the location code in Table 1, second column for the symbolic FRU location code in the FRU list.
  5. Convert the three-character location code from the prior step to a physical location of the I/O enclosure in the rack. See Figure 1.
    Figure 1. I/O enclosure locations in front of rack
    I/O enclosure locations in front of rack

    9. Click Save Settings.
  10. Update the HMC microcode objects for the I/O enclosure machine/type/model/serial number by using a pseudo repair of the PCIe and SPCN card FRU. The update causes the I/O enclosure to be power-cycled.
    1. From the navigation area, click Storage Facility Management > storage facility.
    2. From the Task area, click Exchange Parts > Exchange IO Enclosure and Components.
    3. Click Show I/O Enclosures and select the enclosure location.
    4. Click Show FRUS.
    5. Select I/O Enclosure PCIe/SPCN Card and then click Exchange FRU.
    6. When prompted to replace the FRU, do not disconnect the PCIe and SPCN cables from the card. Do not remove the card.

      Continue the repair.

    7. If the repair is successful, exit this MAP and ensure that any related serviceable events are closed.
    8. If the repair fails with the same error, replace the I/O enclosure PCIe / SPCN card.

About this task

The serviceable event FRU list that sent you here contains one or more cables and possibly more FRUs.
Important: Both ends of each PCIe cable are displayed in the FRU list. Only the first cable location code is available to select for repair or replace for each cable in the FRU list. The subsequent CBLCONT location code shows where a cable continues to connect to, but is not available to select for repair or replace.

Procedure

  1. Inspect both ends of each PCIe cable listed in the FRU list.
    1. Do not plug or unplug the cable.
    2. Refer to Figure 2, Figure 3, and Figure 4 cabling diagrams based on the number of installed I/O enclosures in the machine. The CBLCONT location code that is listed is the port on the I/O enclosure where the cable is supposed to be connected.

      Based on the appropriate cable figure, check each end of the cable that is listed on the screen that sent you here to ensure that it is properly plugged into the correct connector.

    3. Observe the body of the cable to ensure that it is not damaged.

  2. Is the PCIe cable properly plugged and not damaged?
    • Yes, go to the next step.
    • No, go to step 5
  3. The cable is properly plugged and is not damaged. Did
    you reach this step after replacing both the I/O enclosure PCIe and SPCN card and the I/O enclosure backplane?
    • No, go to the next step.
    • Yes, a pseudo-repair of the PCIe and SPCN card might recover this condition. Continue with the following steps:
      1. Return to the screen that sent you here.
      2. To the question, "What was the result of using the service procedure from Infocenter?" click Problem not fixed and then click Next.
      3. To the question, "Did you exchange any parts,?" click No and then click Next.
      4. To the question, "Did you isolate the problem,"? click Yes and then click Next.
      5. The current repair action ends, but the serviceable event remains open. Use
        the Exchange Parts menu to complete a pseudo-repair of the I/O enclosure PCIe and SPCN card:
        • Storage Facility Management > > storage facility > > Exchange Parts

        Remove I/O enclosure power when instructed to do so in the exchange procedure, but you do not need to uncable or remove the PCIe and SPCN card.
  4. The cable is properly plugged and is not damaged. The
    I/O enclosure PCIe and SPCN card and the I/O enclosure backplane were not both replaced.
    1. Return to the screen that sent you here.
    2. To the question, "What was the result of using the service procedure from Infocenter?" click Problem not fixed and then click Next.
    3. To the question, "Did you exchange any parts?" click No and then click Next.
    4. To the question, "Did you isolate the problem?" click No and then click Next.
    5. The next FRU in the list is displayed. Continue the repair by replacing the remaining FRUs until the problem is fixed. Exit this MAP.
  5. The cable is incorrectly plugged or damaged. Start of changeDid a failed IO enclosure installation lead you to this MAP?End of change
    • Start of changeYes
      1. Exit this repair.
      2. Retry the original MES installation with cables properly connected.
      End of change
    • Start of changeNo, the incorrect plugging of the cable or damage to the cable occurred during a repair.
      1. Return to the screen that sent you here.
      2. To the question, "What was the result of using the service procedure from Infocenter?" click Problem not fixed and then click Next.
      3. To the question, "Did you exchange any parts?" click No and then click Next.
      4. To the question, "Did you isolate the problem?" click No and then click Next.
      5. When the next FRU in the list is displayed, pretend that the other FRUs in the previous FRU list are not available onsite to be replaced.
      6. When asked if the FRU is available to be replaced, answer no. This answer causes each FRU in the list to be displayed until the incorrectly plugged cable or the damaged cable is displayed.

        When the incorrectly plugged cable or the damaged cable is displayed, do a normal FRU replace.

      7. When the repair is complete, exit this MAP.
