Before you begin

Note: Storage complex repair actions must always be managed from the management console. To replace any FRUs identified in this procedure, use Storage Facility Management > storage facility > Exchange Parts. If the FRUs are listed in this or another Serviceable Event, select them from there.

Procedure

  1. Is the reference code 1xxx8430, 8431, or 8432?
    • Yes, go to step 4.
    • No, go to step 2.
  2. Is the reference code 1xxx840D or 840E?
    • Yes, go to step 3.
    • No, return to the serviceable event and perform the following:
      • If there are additional FRUs, continue with the next one.
      • If there are no additional FRUs, look for other open serviceable events to repair.
      • If there are no other serviceable events, contact your next level of support.
      This ends the procedure.
  3. Perform PWR1917 to set the correct configuration ID. This ends the procedure.
  4. Is the reference code 1xxx8430?
    • Yes, verify that the service processor cable between the CEC enclosures is connected and seated correctly. If the reference code prevails, replace the following, one at a time:
      1. Service processor card cable (see Exchanging parts)

      This ends the procedure.
    • No, go to step 5.
  5. Is the reference code 1xxx8431?
    • Yes, remove the cable that is not needed for system configuration. If a nonconfigured cable is not present, replace the system backplane (see Exchanging parts). This ends the procedure.
    • No, go to step 6.
  6. Is the reference code 1xxx8432?
    • Yes, the number of secondary units is not correct. Go to PWR1917 to check the system configuration. This ends the procedure.
