If all of the reference codes are 0000, go to "LIC-PIP 11" on page 350
and use cause code 0002. If any of the reference codes are not 0000, go
to step 5 of this procedure 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 "Product Activity Log" in the iSeries
Service Functions information).
Is an SRC logged as a result of this IPL?
Yes 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 in "Chapter 2.
Unit Reference Codes" on page 59). If the failing item list contains FI
codes, see "Failing Items" on page 479 to help determine part numbers
and location in the system.
This ends the procedure.
5. Record the SRC on the Problem Summary Form (see "Appendix A. Problem
Summary Form" on page 951).
Is the SRC the same one that sent you to this procedure?
Yes No
↓
A different SRC or reference code occurred. Use the new SRC or
reference code to correct the problem (see "Starting Point for All
Problems" on page 4).
This ends the procedure.
6. Determine the device unit reference code (URC) from the SRC. If the Disk
Configuration Error Report display or 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. (See "Stage 1 System
Reference Code (SRC) Definition" in the iSeries Service Functions information).
Is the device unit reference code 3020?
Yes No
↓
Go to step 8 of this procedure.
7. 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.
Find the printout that shows the system configuration from the last IPL and
compare it to the present system configuration.
Note: Use the unit address and the physical address in the SRC to help you
with this comparison. If configuration is not the problem, a device on
the SCSI bus may be failing. Use FI code FI00884 to help find the
failing device. If you need to perform isolation on the SCSI bus, go to
"SDIOP-PIP16" on page 407.
This ends the procedure.
8. The possible failing items are FI codes FI01105 (90%) and FI01112 (10%).
