状態に入れないという問題がある。As described above, since the line connection at the time of starting the device in the conventional example detects the stop of the device of the other system and makes a request for the line connection to the own system device, the connection is made. If the two processing units are started up with a small time difference while each other system monitoring line that detects the stop of the system device continues to detect the stopped state due to a failure, the following problems occur. FIG. 3 shows a system startup sequence in such a case. First, when the 0-system information processing apparatus 1 starts to start up, the system switching request is issued to the line switching unit 3 because the stop of the other system is detected. In response to this, the line switch 3 connects the line to the 0-system device 1. On the other hand, when the 1-system device 2 starts to start up after a short delay, the other-system stoppage is detected, so that the line switching device 3 is requested to connect itself. In response to this, the line switch 3 connects the line to the 1-system device 2 this time. After that, when the 0-system device 1 reads out the connection state, it is not the self-system connection, so the self-system connection request is issued again to connect to the self-system.
Such operations are repeated each other, and there is a problem that startup cannot be performed and operation cannot be performed.
