IOPIP18

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 before continuing with this procedure.
2. Perform an IPL to DST. See Performing an IPL to DST.

   Does an SRC appear on the control panel?

   • Yes: Go to step 5.
   • No: 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: Go to step 4.
3. Does one of the following messages appear in the list?
   • Missing disk units in the configuration
   • Missing mirror protection disk units in the configuration
   • Device parity protected units in exposed mode.
     • No: Continue with the next step.
     • Yes: Select option 5, press F11, and then press Enter to display the details. 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 5, and use the reference code that is not 0000.
         Note:
         Use the characters in the Type column to find the correct reference code table.
4. Look at the product activity log (see (Log) for details).

   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 in the failing item column in the reference code list. If the failing item list contains FI codes, see Locating FRUsto help determine part numbers and location in the system. This ends the procedure.
5. Record the SRC.

   Is the SRC the same one that sent you to this procedure?

   • Yes: Continue with the next step.
   • No: A different SRC or reference code occurred. Use the new SRC or reference code to correct the problem. This ends the procedure.
6. Determine the device unit reference code (URC) from the SRC. If the Disk Configuration Error Report, the Disk Configuration Attention Report, or the Disk Configuration Warning Report display appears on the console, the device URC is displayed under Reference Code. This is on the same line as the missing device.

   Is the device unit reference code 3020?

   • No: Continue with the next step.
   • Yes: A device reference code of 3020 indicates that a device is attached to the addressed I/O card. Either it is not supported, or it does not match system configuration rules. For example, there are too many devices that are attached to the bus. Perform the following steps:
     1. Find the printout that shows the system configuration from the last IPL and compare it to the present system configuration.
     2. Use the unit address and the physical address in the SRC to help you with this comparison.
     3. If configuration is not the problem, a device on the SCSI bus may be failing. Use FI code FI00884 in the Locating FRUs table to help find the failing device.
     4. If you need to perform isolation on the SCSI bus, go to IOPIP16. This ends the procedure.
7. The possible failing items are FI codes FI01105 (90%) and FI01112 (10%).

   Find the device unit address from the SRC. Use this information to find the physical location of the device. Record the type and model numbers to determine if the addressed I/O card supports this device.

   Is the device given support on your system?

   • No: Continue with the next step.
   • Yes: Perform the following steps:
     1. Exchange the device.
     2. Perform an IPL to DST. See Performing an IPL to DST.

     Does this correct the problem?

     • No: Ask your next level of support for assistance. This ends the procedure.
     • Yes: This ends the procedure.
8. Perform the following steps:
   1. Remove the device.
   2. Perform an IPL to DST. See Performing an IPL to DST.

   Does this correct the problem?

   • No: Ask your next level of support for assistance. This ends the procedure.
   • Yes: This ends the procedure.
