PROBLEM TO BE SOLVED: To achieve the computer stop and computer reset stop of an operation system computer in which any failure has occurred, by receiving a telegraphic message one time from a standby system computer.SOLUTION: Each of a plurality of computers constituting a system includes: another system monitoring means 113 for monitoring the existence of the other system computer; and a system switching control (LXP) board 110 having computer reset control means and a computer reset stop timer. In the LXP board of an operation system computer, when receiving a computer stop telegraphic message from a standby system computer in accordance with the occurrence of any failure in the operation system computer, the computer reset stop means of the operation system computer transmits a non-maskable interruption signal to the other system monitoring means of the operation system computer, and starts a computer reset stop timer. When receiving the non-maskable interruption signal, the other system monitoring means of the operation system computer starts the processing of the storage of the failure information of the operation system computer in which the failure has occurred, and when the storage of the failure information is not possible, and the computer reset stop timer times up, makes the operation system computer perform reset stop. |
