ABSTRACT:
A method and apparatus for correlating the identities of hardware devices, such as processors and memory controllers, between a local operating system and a global management entity is described. When the operating system detects a faulting device, the operating system generates a fault message and transmits the fault message to the global management entity. The global management entity determines the identity of the faulting device based on information contained in the fault message, selects an appropriate replacement device, changes a routing table to map to the replacement device to the identity of the faulting device, and transmits to the operating system a global identity of the replacement device. The operating system correlates the local identity of the replacement device with the global identity of the replacement device.
