A method and system for migrating at least one critical resource during a migration of an operative portion of a computer system are disclosed. In at least some embodiments, the method includes (a) sending first information constituting a substantial copy of a first of the at least one critical resource via at least one intermediary between a source component and a destination component. The method further includes (b) transitioning a status of the destination component from being incapable of receiving requests to being capable of receiving requests, and (c) re-programming an abstraction block to include modified addresses so that at least one incoming request signal is forwarded to the destination component rather than to the source component.

Method and system for migrating critical resources within computer systems

A method and system for handling interrupts within a computer system during hardware resource migration are disclosed. In at least some embodiments, the method includes (a) programming an address conversion component so that incoming interrupt signals are directed to a control component rather than to a source processing resource, and (b) accumulating the incoming interrupt signals at the control component. Additionally the method also includes, subsequent to the migration of the partition from the source processing resource to a destination processing resource, (c) sending the accumulated incoming interrupt signals to the destination processing resource, and (d) reprogramming the address conversion component so that further incoming interrupt signals are directed to the destination processing resource.
