IOPIP13

Use this procedure to isolate problems on the interface between the I/O card and the storage devices.

The unit reference code (part of the SRC that sent you to this procedure) indicates the SCSI bus that has the problem:
Unit reference code (URC) SCSI bus
3100 0
3101 1
3102 2
3103 3
  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 if the system has logical partitions.
  2. Were you performing an IPL from removable media (IPL type D) when the error occurred?
    • No: Continue with the next step.
    • Yes: Exchange the FRUs in the failing item list for the reference code that sent you to this procedure. This ends the procedure.
  3. Perform the following steps:
    1. Look in the service action log (see Searching the service action log ) for other errors logged at or around the same time as the 310x SRC.
    2. If no entries appear in the service action log, use the product activity log (see Using the product activity log ).
    3. Use the other SRCs to correct the problem before performing an IPL.
    4. Contact your next level of support as necessary for assistance with SCSI bus problem isolation.
    5. If the problem is not corrected, continue with the next step.
  4. 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 7.
  5. Does one of the following displays appear on the console?
    • Disk Configuration Error Report
    • Disk Configuration Attention Report
    • Disk Configuration Warning Report
    • Display Unknown Mirrored Load-Source Status
    • Display Load-Source Failure

      Is an SRC logged as a result of this IPL?

      • Yes: Continue with the next step.
      • No: 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 failing item list for this reference code. If the failing item list contains FI codes, see the System FRU locations topic to help determine part numbers and location in the system. This ends the procedure.
  6. Are all of the reference codes 0000? On some of the displays, you must press F11 to display reference codes.
    • No: Continue with the next step. Use the reference code that is not 0000.
    • Yes: Go to LICIP11 and use cause code 0002. This ends the procedure.
  7. Is the SRC the same one that sent you to this procedure?
    • Yes: Continue with the next step.
    • No: Record the SRC. Then use the SRC description to correct the problem. This ends the procedure.
  8. Perform the following:
    1. Power off the system or the expansion tower. See Powering on and powering off the system for details.
    2. Find the I/O card identified in the failing item list.
    3. Remove the I/O card and install a new I/O card. This item has the highest probability of being the failing item.
    4. Power on the system or the expansion tower.

    Does an SRC appear on the control panel?

    • No: Continue with the next step.
    • Yes: Go to step 12.
  9. Does one of the following displays appear on the console?
    • Disk Configuration Error Report
    • Disk Configuration Attention Report
    • Disk Configuration Warning Report
    • Display Unknown Mirrored Load-Source Status
    • Display Load-Source Failure
    • Yes: Does the Display Unknown Mirrored Load-Source Status display appear on the console?
      Note: On some of these displays, you must press F11 to display reference codes.
      • Yes: Continue with the next step.
      • No: Are all of the reference codes 0000?
        • No: Go to step 12 using the reference code that is not 0000.
        • Yes: Go to LICIP11 and use cause code 0002. This ends the procedure.
    • No: Go to step 11.
  10. Is the reference code the same one that sent you to this procedure?
    • No: Either a new reference code occurred, or the reference code is 0000. There may be more than one problem. The original I/O card may be failing, but it must be installed in the system to continue problem isolation. Install the original I/O card by doing the following:
      1. Power off the system or the expansion tower. See Powering on and powering off the system for details.
      2. Remove the I/O card you installed in step 8 and install the original I/O card.
        Note: Do not power on the system or the expansion unit now.

        A device connected to the I/O card could be the failing item. Go to IOPIP16, step (9) to continue isolating the problem. This ends the procedure.

    • Yes: Go to step 13.
  11. 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 I/O card, which you removed in step 8, is the failing item. This ends the procedure.
  12. Is the SRC or reference code the same one that sent you to this procedure?
    • Yes: Continue with the next step.
    • No: Record the SRC. Then use the SRC description to correct the problem. This ends the procedure.
  13. The original I/O card is not the failing item. Install the original I/O card by doing the following:
    1. Power off the system or the expansion tower. See Powering on and powering off the system for details.
    2. Remove the I/O card you installed in step 8 of this procedure and install the original I/O card.
      Note: Do not power on the system or the expansion unit now.

    A device connected to the I/O card could be the failing item. Go to IOPIP16, step (9) to continue isolating the problem. This ends the procedure.
