Maintenance Procedures Using Maintenance Log Functions

       Described are new maintenance procedures using
maintenance log functions for improving serviceability.

      When an error occurs in a system, the error information is
recorded in a error log area which is usually in non-volatile memory
in the device.  The error log is used to analyze a problem by a
repairman.  However, the repairman cannot obtain enough information
from this log to solve the problem.  It is also necessary that the
repairman be familiar with the maintenance history to perform an
appropriate maintenance action.

      A repairman may have been recording his maintenance log
somewhere, e.g., in his notebook.  However, if no other repairmen can
read it, it is not helpful to them even though useful information has
been logged.

      The figure shows the contents of logs which are used in the new
maintenance procedure.

      The log functions provide not only error log, but also
maintenance log in which past maintenance information is kept.
Therefore, it is possible for a repairman to determine the cause of
the problem by analyzing both of the logs.  The maintenance log
consists of a maintenance event log and a  maintenance bulletin.

      When the following maintenance events occur, event information
is logged in the maintenance event log automatically.
      -  Power on
      -  Usage of the reset function
      -  Removal of subsystem cards
