Abstract

Disclosed is a Service Request Number (SRN) Architecture developed to cover multiple system unit types and packaging schemes. This architecture meets the following requirements: Covers a wide range of system units from table-top system units to rack-mounted system units Provides the capability of easily translating Failing Functions Code numbers into Part Numbers of possible failing FRUs (Field Replaceable Units) Handles the different ways a given function is packaged within the different types of system units Is user friendly - Identifies all of the FRUs that are likely to cause the problem Identifies the probability percentage of each FRU being the failing FRU.

Service Request Number Architecture

      Disclosed is a Service Request Number (SRN) Architecture
developed to cover multiple system unit types and packaging schemes.
This architecture meets the following requirements:
  Covers a wide range of system units from table-top system units to
rack-mounted system units
  Provides the capability of easily translating Failing Functions
Code numbers into Part Numbers of possible failing FRUs (Field
Replaceable Units)
  Handles the different ways a given function is packaged within the
different types of system units
  Is user friendly
- Identifies all of the FRUs that are likely to cause the problem
  Identifies the probability percentage of each FRU being the failing
FRU.

      DESCRIPTION OF THE INVENTION

      There are three major items associated with this architecture:
        The Service Request Number (SRN)
      - The Failing Function Code (FFC) number
      - The Three-Digit Display Codes.

      SERVICE REQUEST NUMBER (SRN)

      The Service Request Number (SRN) is a two-part, six-digit
number (example, 104-210) that identifies a given problem.  The first
three digits of the SRN identify the Source Number of the SRN, while
the second three digits are the Reason Code.  For example, SRN
104-210 is broken down into two parts:
104-210
 @   @
 @   +------ Reason Code
 +---------- Source Number

      The Source Number identifies what testing or problem analysis
generated the SRN. The following table describes how the Source
Numbers are generated:
000 to 100 - Reserved
101 -        The SRN is generated by the Service Documentation when a
solid Three-Digit Display number is present
102 -        Reserved
103 -        The SRN is generated during software problem
determination
104 -        The SRN is generated by the Power-On Self-Test (POST)
105 -        The SRN is read out after the system unit halted with a
blinking '888' in the Three-Digit Display
106 to 110 - Reserved
111 -        The SRN is generated by the Service Documentation for
problems other than a solid Three-Digit Display.  An example would be
a power problem.
112 to 200 - Reserved
201 to 210 - The SRN is generated by POST
211 to 800 - Reserved
801 -        The SRN is generated by the Diagnostic Controller when
no Three-Digit Display number is available.
802 -        The SRN is generated by the Diagnostic Controller for a
missing device
803 -        The SRN is generated by the Diagnostic Controller when a
software error is detected while running a Diagnostic Application
805 to 810 - Reserved
811 to 999 - The SRN is generated by the Diagnostic Controller and
Diagnostic Application during testing

      The second three digits of the SRN are called the Reason Code.
The following table describes how the Reason Code number is
generated:
101 -        The Reason Code is the same as the number displayed in
the T...
