Unextending a Hierarchy
The LifeKeeper Unextend Resource Hierarchy option removes a complete hierarchy, including all
of its resources, from a single server. This is different than the Delete Resource Hierarchy selection
which removes a hierarchy from all servers.
When using Unextend Resource Hierarchy, the server from which the existing hierarchy is to be
removed is referred to as the target server.
The Unextend Resource Hierarchy selection can be used from any LifeKeeper server that has
active LifeKeeper communications paths to the target server.
