MAP4095 CEC enclosure processor core problem

Edit online

CEC enclosure processor core problem. One or more cores have been deconfigured. Errors that call this MAP normally occur only while running View storage facility state (end of call), CDA pre-verify, or CDA code load.

Procedure

  1. Are you in the middle of a processor upgrade MES that changes the CEC enclosure processor module(s)?
    • Yes, go to the next step.
    • No, go to step 4.
  2. Have you just finished changing the processor modules in the first CEC enclosure?
    • Yes, go to the next step.
    • No, go to step 4.
  3. The processor module(s) in the first CEC enclosure have been upgraded and the processor module(s) in the second CEC have not. There is a processor module mismatch between the two CEC enclosures. Find the SRC in the serviceable event that sent you here.
    • Read the MES to determine whether a CEC enclosure processor mismatch error is expected and should be ignored.
    • Read the SRC definition to see whether it says that there is a processor mismatch. This might be normal.
    • Display open serviceable events to see whether there are any other serviceable events that include processor modules in the FRU list. If there are, use that serviceable event to repair the problem.
    • Call the next level of support for help.
  4. Go to MAP4095 Section-2.

Procedure

  1. Display open serviceable events for the CEC enclosure. Other than the serviceable event that sent you to this MAP, is there any other related open serviceable event that lists the processor modules as FRUs?
    • Yes, exit this MAP and repair the related serviceable event. If the repair is successful, remember to close the serviceable event that sent you here. If you were doing a processor upgrade MES, exit this MAP and continue the MES now.
    • No, go to the next step.
  2. Log in to the ASM menu for the failing CEC enclosure.
    1. To determine the CEC enclosure that is failing, observe the FRU location code for the processor module in the serviceable event FRU list.
    2. Type admin in the User ID field and admin2107 in the Password field. If the login fails, log in as admin with a password of admin210.
      See MAP6F10 Accessing the ASMI using the management console.
  3. Display the error and event logs to determine any related problems.
    1. Select System Service Aids > Error/Event logs.
    2. Display the log details and look for information that is related to processor module or processor core errors or locations.
    3. Are there any logs that identify a failing processor module or processor module core?
      • Yes, if you can determine the failing processor module FRU, exit this MAP and use Storage Facility Management > storage facility > Exchange Parts to replace the processor module.
      • No, go to the next step.
  4. Display the processor deconfiguration status.
    1. Select System Configuration > Hardware Deconfiguration > Processor Deconfiguration. The total processors, configured processors, and deconfigured processors are displayed.
    2. Are there any deconfigured processors?
      • Yes, go to step 6.
      • No, go to the next step.
  5. Compare the total processors for the failing CEC enclosure to the working CEC enclosure. Are there any differences between the number of processors?
    • Yes, go to the next step.
    • No, exit this MAP and contact your next level of support. The serviceable event that sent you here indicates a processor problem was detected, yet all processors appear to be available.
  6. Display the details.
    1. Click the radio button of the Processing Unit.
    2. Click Continue. The status and location code for each processor ID is displayed.
  7. Are any processor IDs deconfigured?
    • Yes, go to the next step.
    • No, exit this MAP and contact your next level of support. The serviceable event that sent you here indicates that a memory problem was detected, yet all memory appears to be available.
  8. Replace the processor module FRU that contains the processor ID that is deconfigured. See Figure 1 (Models 993, 994, A01) or Figure 2 (Models 996, 998, A05).
    1. There are one or two processor modules in a CEC enclosure.
      • P1-C47 is always present.
      • P1-C48 is always present in Models 993, 994, A0x.
      • P1-C48 is optional in Models 996, 998 based on installed features.
    2. Exit this MAP and return to the management console screen that sent you here.

      Do a normal repair of the processor module by selecting the next FRU in the FRU list.

      The FRU list always lists the P1-C47 location code, even when the P1-C48 processor module has a deconfigured processor ID. You can use the P1-C47 location code to replace the P1-C48 FRU.
