Mechanism for Capturing Failure Data within a Replaceable Machine
Element

      Described is a method for insuring that failure data associated
with a failing FRU is captured and recorded on the FRU itself without
manual intervention.  In the following description, refer to the
Figure.

      All elements (A & D's) that are candidates for return to a
repair center are fitted with a Non-Volatile Memory (NVRAM) component
(F).  When an error occurs, it is either detected by, or reported to,
the box management element (A).  Subsequently, a programming task (B)
is started that gathers the pertinent data relating to the error and
stores the data in the NVRAM (F) on the part that is suspected to be
the cause of the error.  The communications path (E) for this error
data is totally separate from the regular operational communications
path (C) within the box.

      The concept of a separate data path adds a significant element
of fault tolerance since there is a class of errors involving the
operational path that would prevent access to the failing part by the
error processing code if the only path to the failing part was the
"operational path".

      This approach guarantees the presence of detailed error data at
the repair facility and eliminates the problems introduced by
dependence on manual documentation preparation.

      The design closely follows the general arrangement given in the
Figure.  The specific details about the implementation of each it...
