The LifeKeeper Extend Resource Hierarchy option copies an existing hierarchy from one server and creates a similar hierarchy on another LifeKeeper server. Once a hierarchy is extended to other servers, cascading failover is available for that resource. The server where the existing hierarchy currently resides is referred to as the template server. The server where the new extended hierarchy will be placed is referred to as the target server.
The target server must be capable of supporting the extended hierarchy and it must be able to communicate with equivalent hierarchies on other remote servers (via active LifeKeeper communications paths). This means that all recovery kits associated with resources in the existing hierarchy must already be installed on the target server, as well as every other server where the hierarchy currently resides.

The Accept Defaults button which is available for the Extend Resource Hierarchy option is intended for the user who is familiar with the LifeKeeper Extend Resource Hierarchy defaults, and wants to quickly extend a LifeKeeper resource hierarchy without being prompted for input or confirmation. Users who prefer to extend a LifeKeeper resource hierarchy using the interactive, step-by-step interface of the GUI dialogs should use the Next button.
