ABSTRACT:
A method of operation within a data processing system that includes a plurality of processing nodes each having access to a set of shared resources. Failure of one of the processing nodes is detected, followed by receipt of a request to access a first resource of the set of shared resources. Access to the first resource is granted if the failed node was not responsible for controlling access to the first resource and did not have exclusive access to the first resource when the failure was detected.
