FSPSP41: Model 570

Shows how to isolate to a failing FRU.

To isolate to a failing FRU do the following:
  1. Record words 3, 7, and 8 from the primary system reference code (SRC) of the error log.
  2. Determine the enclosure that contains the service processor that started the I2C operation.
    Note: The remainder of this procedure refers to this enclosure as the FSP enclosure.
    Refer to the last byte in word 3 of the primary SRC to find the service processor enclosure:
    1. If the last byte is a 10, then the primary unit service processor started the I2C.
    2. If the last byte is a 20, then the secondary unit 1 service processor started the I2C.
    3. If the last byte is a 30, use one of the following methods to determine the enclosure:

      If you have access to the Advanced System Management Interface (ASMI), log on and display the details of the service processor error log. Using the Platform Event Log id (shown in the first table of each detail of the log), look at the first byte.

      • If the first byte is a 50, then the primary unit service processor started the I2C.
      • If the first byte is a 51, then the secondary unit 1 service processor started the I2C.

      If you have access to an Hardware Management Console (HMC), log in as PE user and bring up Manage Serviceable Events under the Service Focal Point screen. Display the events for the corresponding service processor system, then double-click the system to see the details. Look at the Field Platform log ID, which contains a decimal value that you need to convert to a hexadecimal value.

      • If the first byte of the hexadecimal value is a 50, then the primary unit service processor started the I2C.
      • If the first byte of the hexadecimal value is a 51, then the secondary unit 1 service processor started the I2C.
  3. Determine which enclosure contains the target I2C device.
    Note: The remainder of this procedure refers to the enclosure that contains the I2C device as the target enclosure.
    In the I2C Target enclosure table, find word 7 from the primary SRC. The enclosure listed beside word 7 is the target enclosures. Click the following link to display the I2C Target enclosure table: I2C Target enclosures for model 570 (4-core or 8-core through 16-core)
  4. Does word 7 have a match in the I2C Target enclosure table?
    • Yes: Continue with the step 6.
    • No: Continue with the next step.
  5. The right most 2 bytes of word 7 does not have a match in the I2C Target enclosure table. Use the following statements to determine which enclosure contains the target I2C device:
    1. If the right most 2 bytes of word 7 is either 0002 or 0003, then the FSP enclosure and the target enclosure are the same.
    2. If the right most 2 bytes of word 7 is either 0000 or 0001, then refer to the following conditions
      1. i. If the FSP enclosure is the primary unit, then the target enclosure is the secondary unit
      2. If the FSP enclosure is secondary unit 1, then the target enclosure is the primary unit.
  6. Determine which parts you need to replace on the target enclosure.
    1. Using the following I2C FRU table for model 570, refer to words 7 and 8 of the primary SRC to locate the I2C FRU list. The I2C FRU list identifies the parts that you need to replace. Click the following link to display the I2C FRU table: I2C FRU table for model 570 (4-core or 8-core through 16-core)
    2. Did you find the I2C FRU list?
      • Yes: Continue with the next step.
      • No: Contact your next level of support. This ends the procedure.
  7. Starting with the first FRU in the list that you located the I2C FRU table, do the following:.
    1. Power off the system.
    2. Replace the FRU on the target enclosure. Go to Finding part locations for location, part number, and exchange information.
    3. Go to Perform a slow boot, then continue with the next step.
    4. Is the problem resolved?
      • Yes: This ends the procedure.
      • No: Continue with the next step.
  8. Have you replaced all of the FRUs in the list?
    • No: Repeat step 7 for the next FRU in the list.
    • Yes: Continue with the next step.
  9. Replace the following FRUs, one at a time and in the order listed. After you replace each FRU, perform a slow boot until the problem is resolved. For more information, see Perform a slow boot.
    1. System/service processor cable connected from the service processor enclosure to the target enclosure
    2. Service processor on the service processor enclosure
    3. I/O backplane on the target enclosure
    4. I/O backplane on the service processor enclosure
  10. Is the problem resolved?
    • Yes: This ends the procedure.
    • No: Contact your next level of support. This ends the procedure.
