Abstract
A data processing system includes system control facilities for monitoring and controlling the system. A first service processor, under program control, drives the system control facilities to perform service functions for the data processing system. A second service processor, independently under program control, also drives the system control facilities to perform service functions for the data processing system. An arbitrating circuit cross-couples each system control facility to the respective service processors and arbitrates the transfer of data and control signals between each given system control facility and the given service function running on the given service processor which currently has possession and control of the given system control facility.
