Abstract

Disclosed is a Logical Maintenance Volume which is used for maintaining a tape library subsystem. Logical Maintenance Volume provides a command interface between an operator and a diagnose subsystem in the library. Logical Maintenance Volume exists in a tape library logically, and it is accessible by a standard access method or utility software, the same as usual tape volume. An operator could write a maintenance command (or command sequence) to Logical Maintenance Volume to demand the command interpretation and execution to the diagnose subsystem. After command execution, the diagnose subsystem writes result to Logical Maintenance Volume, then the operator could retrieve the executed result by reading data records on the volume.

Logical Maintenance Volume for Maintaining a Tape Library

      Disclosed is a Logical Maintenance Volume which is used for
maintaining a tape library subsystem.  Logical Maintenance Volume
provides a command interface between an operator and a diagnose
subsystem in the library.  Logical Maintenance Volume exists in a
tape library logically, and it is accessible by a standard access
method or utility  software, the same as usual tape volume.  An
operator could write a maintenance command (or command sequence) to
Logical Maintenance Volume  to demand the command interpretation and
execution to the diagnose subsystem.  After command execution, the
diagnose subsystem writes result  to Logical Maintenance Volume, then
the operator could retrieve the executed result by reading data
records on the volume.

      The existing method to maintain a tape library and its
contained tape volumes requires additional programs/procedures which
are new functions of the data management subsystem on the operating
system, tape library maintenance software or a manual procedure at an
operator console of a tape library, etc..  However, the following
problems can occur:
  1.  Adding a new function of data management subsystem is a
       concern since losing stability of the operating system,
       because of system impact, is considerable.
  2.  Adding a new tape library maintenance program requires a
       change of operation procedure.  Besides, education of an
       operator is necessary.
  3.  A manual operation at an operator console can possibly
       cause human misoperation, and it is difficult to keep
       an operation log and results.

Logical Maintenance Volume solves the above problems and gains the
following advantages:
  1.  Logical Maintenance Volume does not require unique
       diagnose software.  Instea...
