Abstract
Methods and systems are provided by which a computer system, and in particular, a lockstep fault-tolerant computer system, may be split into a plurality of independently operational subsystems. Each subsystem may be examined, managed or upgraded by an administrator while the overall computer system continues to service end-users. Finally, the separate subsystems may be merged in an efficient fashion and fault-tolerant operation will resume upon the combined system.
