Chapter 15: Grouping Units 211
There are two top-level system-defined unit group containers: global root and personal root. These
group containers cannot be deleted. They can contain other unit groups, but not individual units. All
global unit groups are descendents of global root. All personal unit groups are descendents of
personal root.
There is also a system-defined unit group named Unassigned, which is a descendent of the global
root. This unit group automatically contains all units that are not assigned to any other global unit
groups. This group cannot be deleted, and you cannot add subgroups (children) to the Unassigned
unit group.
Global unit groups may only be created, modified or deleted by users with DSView 3 software
administrator, user administrator or appliance administrator privileges. The global root, personal
root and unassigned unit groups cannot be deleted.
