PROBLEM TO BE SOLVED: To provide a technology for, when a failure occurs in a current system server device, allowing a standby system server device to quickly rise as a current system instead of the server device.SOLUTION: A server device 1 includes a control circuit 2, a mechanical control circuit 3, a failure detection circuit 4 and a connection control circuit 5. The control circuit 2 is configured to execute processing based on a computer program including processing for controlling its connection with a shared resource 8. The failure detection circuit 4 includes a circuit configuration for detecting that a failure occurs in the own device 1. The connection control circuit 5 is configured to, when failure occurrence is detected by the failure detection circuit 4, interrupt its connection with the shared resource 8 before the control circuit 2 instructs the interruption of its connection with the shared resource 8. The mechanical control circuit 3 is configured to, when the failure occurrence is detected by the failure detection circuit 4, notify the other server device 1 of the failure occurrence. |
