Abstract
According to one embodiment, a method comprises, responsive to detection of loss of lockstep (LOL) for a processor module in a system, setting status information stored to the system for the processor module to indicate that the processor module has an error. The method further comprises reestablishing lockstep for the processor module without shutting down the system's operating system, and updating the status information for the processor module to indicate that the processor module no longer has the error. The method further comprises causing the system's operating system to recognize that the processor module having its lockstep reestablished is available for processing.
