Abstract
A method and apparatus for correlating the identities of hardware devices, such as processors or memory controllers, between a local operating system and a global management entity is described. In an embodiment a fault message including a local identifier of a faulting device is received from an operating system. A global identifier of the faulting device is determined that is different from the local identifier. An appropriate replacement device is then selected based on the global identifier of the faulting device, and the selected replacement device is mapped to the faulting device.
