<p>A subject of the present invention is to perform stuck-at control in a data processing system having system boards that process data, a crossbar unit having control units to control communication between each system board, and a system controller without causing an availability ratio of a computer system to fall. For that purpose, when a control unit fails, the crossbar unit sends, among IDs uniquely attached to each system board, the ID of each system board under the control of the failed control unit to the system controller. The system controller determines to which of partitions that logically divide a system each system board corresponding to the ID received from the crossbar unit belongs and sends a stop command to stop driving of each system board belonging to the determined partition.</p> |
