This object when set to 'basic(1)', results in
the zone server operating in the basic mode
as defined by FC-GS4 standards.
This object when set to 'enhanced(2)', results in
the zone server operating in the enhanced mode
as defined by FC-GS4 standards.
The local zone server can move to the enhanced
mode of operation only if all devices in the
Fibre Channel fabric are capable of working in
enhanced mode.
Otherwise, the set operation trying to set this
