IOPIP01

Use this procedure to perform an IPL to dedicated service tool (DST) to determine if the same reference code occurs.

1. If the system has logical partitions, perform this procedure from the logical partition that reported the problem. To determine if the system has logical partitions, go to Determining whether the system has logical partitions, before continuing with this procedure.
2. Was the IPL performed from disk (Type A or Type B)?
   • No: Continue with the next step.
   • Yes: Go to step 5.
3. Perform the following steps:
   1. Ensure that the IPL media is the correct version and level that are needed for the system model.
   2. Ensure that the media is not physically damaged.
   3. Choose from the following options to clean the IPL media:
      • If it is cartridge type optical media (for example, DVD), do not attempt to clean the media.
      • If it is non-cartridge type media (for example, CD-ROM), wipe the disc in a straight line from the inner hub to the outer rim. Use a soft, lint-free cloth or lens tissue. Always handle the disc by the edges to avoid finger prints.
      • If it is tape, clean the recording head in the tape unit. Use the correct Cleaning Cartridge Kit provided by your service provider.
4. Perform a Type D IPL in Manual mode.
   Does a system reference code (SRC) appear on the control panel?

   • No: Go to step 8.
   • Yes: Is the SRC the same one that sent you to this procedure?
     • Yes: You cannot continue isolating the problem. Use the original SRC and exchange the failing items, starting with the highest probable cause of failure. See the reference code list. If the failing item list contains FI codes, see Part locations and location codes to help determine part numbers and location in the system. This ends the procedure.
     • No: A different SRC occurred. Use the new SRC to correct the problem. See Starting a repair action. This ends the procedure.
5. Perform an IPL to DST. See Performing an IPL to dedicated service tools.
   Does an SRC appear on the control panel?

   • No: Continue with the next step.
   • Yes: Go to step 10.
6. Does either the Disk Configuration Error Report, the Disk Configuration Attention Report, or the Disk Configuration Warning Report display appear on the console?
   • No: Continue with the next step.
   • Yes: Select option 5, press F11, then press Enter to display the details. Then, choose from the following options:
     • If all of the reference codes are 0000, go to LICIP11 and use cause code 0002.
     • If any of the reference codes are not 0000, go to step 10, and use the reference code that is not 0000.
       Note: Use the characters in the Type column to find the correct reference code table.
7. Look at the product activity log. See Using the product activity log for details.
   Is an SRC logged as a result of this IPL?

   • Yes: Continue with the next step.
   • No: The problem cannot be isolated any more. Use the original SRC and exchange the failing items. Start with the highest probable cause of failure in the failing item list for this reference code. If the failing item list contains FI codes, see Part locations and location codes to help determine part numbers and location in the system. This ends the procedure.
8. Does either the Disk Configuration Error Report, the Disk Configuration Attention Report, or the Disk Configuration Warning Report display appear on the console?
   • Yes: Continue with the next step.
   • No: Look at the product activity log. See Using the product activity log for details.
     Is an SRC logged as a result of this IPL?

     • Yes: Continue with the next step.
     • No: The problem is corrected. This ends the procedure.
9. Select option 5, press F11, then press Enter to display the details. Then, choose from the following options:
   • If all of the reference codes are 0000, go to LICIP11 and use cause code 0002.
   • If any of the reference codes are not 0000, continue with the next step and use the reference code that is not 0000.
     Note: Use the characters in the Type column to find the correct reference code table.
10. Record the SRC.
    Are the SRC and unit reference code (URC) the same ones that sent you to this procedure?

    • Yes: Continue with the next step.
    • No: Use the new SRC or reference code to correct the problem. This ends the procedure.
11. Perform the following steps:
    1. Power off the system or expansion unit. See Powering on and powering off the system.
    2. Exchange the FRUs in the failing item list for the SRC you have now. Start with the highest probable cause of failure in the failing item column in the reference code list. Perform the remaining steps of this procedure after you exchange each FRU until you determine the failing FRU.
       Note: If you exchange a disk unit, do not attempt to save customer data until instructed to do so in this procedure.
12. Power on the system or the expansion unit. See Powering on and powering off the system.
    Does an SRC appear on the control panel?

    • No: Continue with the next step.
    • Yes: Go to step 16.
13. Does either the Disk Configuration Error Report, the Disk Configuration Attention Report, or the Disk Configuration Warning Report display appear on the console?
    • Yes: Continue with the next step.
    • No: Look at the product activity log. See Using the product activity log for details.
      Is an SRC logged as a result of this IPL?

      • Yes: Continue with the next step.
      • No: The last FRU you exchanged was failing.
        Note: Before exchanging a disk unit, you should attempt to save customer data.

        This ends the procedure.

14. Select option 5, press F11, then press Enter to display the details. Then, choose from the following options:
    • If all of the reference codes are 0000, go to LICIP11 and use cause code 0002.
    • If any of the reference codes are not 0000, go to step 10, and use the reference code that is not 0000.
      Note: Use the characters in the Type column to find the correct reference code table.
15. Record the SRC on the Problem summary form. See Using the product activity log for details.
    Is the SRC the same one that sent you to this procedure?

    • Yes: The last FRU you exchanged is not the failing FRU. Go to step 12 to continue FRU isolation.
    • No: Is the SRC B100 4504 or B100 4505 and have you exchanged disk unit 1 in the system unit, or are all the reference codes on the console 0000?
      • Yes: The last FRU you exchanged was failing. This ends the procedure.
        Note: Before exchanging a disk unit, you should attempt to save customer data.
      • No: Use the new SRC or reference code to correct the problem. This ends the procedure.
