Note: The sample MO Tree Hierarchy, shown above, illustrates only a sample
containing the most basic and widely-used MOs. The actual configuration typically
contains hundreds of MOs, representing different physical and logical resources.

Each MO has an Operational State and an Administrative State.
Operational State – describes the factual operability of the corresponding
resource. It has two possible values – enabled and disabled.
Administrative State – describes the user-desired operability of the
corresponding resource. It has three possible values – locked, shuttingDown and
unlocked.
