This MIB provides objects for upgrading images on modules in the
system, objects for showing the result of an upgrade operation,
and objects for showing the result of a test operation.

To perform an upgrade operation, a management application
must first read the hh3cIssuUpgradeImageTable table and use the
information in other tables, as explained below.  You can
configure a new image name for each image type as listed in
hh3cIssuUpgradeImageTable.  The system will use this image on the
particular module at the next reboot.

The management application used to perform an upgrade
operation must first check if an upgrade operation is already
in progress in the system.  This is done by reading the
hh3cIssuOpType ('none' indicates that
no other upgrade operation is in progress.  Any other value
indicates that an upgrade is already in progress and a new upgrade
operation is not allowed.  To start an 'install' operation,
the user must first perform a 'test' operation to examine the
version compatibility between the given set of images
and the running images.  Only if the result of the 'test'
operation is 'success' can the user proceed to do an install
operation.  The table hh3cIssuTestResultTable
provides the result of the 'test' operation performed by using hh3cIssuOpType.
The table hh3cIssuUpgradeResultTable provides the result of the 'install' operation
performed by using hh3cIssuOpType.
