Specifying an Origin
Assume that the backup partition has specified an origin, minimal initial storage, and a large amount of reserved storage. Since the backup system does not own its complete addressable range, two other partitions, are defined in the reserved storage of the backup partition. See Figure 1 for the storage layout before nonspecific deactivation.

Assume that the backup LP has been given cross partition authority. See Figure 2 for the storage layout at the completion of a takeover by the backup LP.
