Using the list of system reference codes and firmware codes

This section describes how to use the list of system reference codes (SRCs) and firmware codes.

About this task

The list of system reference codes is organized in hexadecimal sequence, with numeric characters listed before alphabetic characters. Each entry in the list represents the first four characters (the reference code type) of the SRC. The entries link to more information, typically a table that lists the unit reference codes (URCs) that are associated with that reference code type.
Unless specified otherwise on a particular SRC page, the SRC tables contain the following columns:
  • The Last four characters of SRC column contains numbers that represent the URC.
  • The Description/Action column offers a brief description of the failure that this SRC represents. It also contains instructions for continuing the problem analysis.
  • The Failing Item column represents functional areas of the system unit. When available, the failing function code links to the FRU that contains this function for each specific system unit.

The steps below show you how to use the list of system reference codes

Procedure

  1. Click the item in the list of system reference codes that matches the reference code type that you want to find.
    Note: The SRC tables support only 8-character reference code formats. If the reference code provided contains only 4 or 6 characters, contact your next level of support for assistance.
  2. When the SRC table appears, select the appropriate URC from the first column of the table. The tables list URCs in hexadecimal sequence with numeric characters listed before alphabetic characters.
  3. If you have a serviceable event which contains FRUs or links to a Symbolic FRU procedure then you must use them to repair the DS8000®. In that case, the information in these tables is provide for reference purposes only. If you are here because you do not have a serviceable event containing FRUs or links to a Symbolic FRU procedure then perform the following actions:
    1. Perform the action indicated for the URC in the Description/Action column of the table.
    2. If the table entry does not indicate an action or if performing the action does not correct the problem, exchange the failing items or parts listed in the Failing Item column in the order that they are listed. Use the following instructions to exchange failing items:
      • Exchange the failing item listed first.
      • If exchanging the first failing item does not correct the problem, reinstall the original item and exchange the next failing item listed.
      • Continue to exchange and reinstall the failing items, one at a time, until the problem is corrected. If exchanging the failing items does not correct the problem, ask your next level of support for assistance.
