<p>PURPOSE:To control power supply without affecting the other host and without caring about an operator even if the state of system operation changes by executing the power supply control of a device. CONSTITUTION:This controller is provided with two hosts which constitute systems (1) and (2), can be combined/separated and become a host C at the time of being combined and hosts A and B at the time of being separated, a group of power supply devices 6 composed of devices which respectively become exclusive to the host A, exclusive to the host B and shared by the hosts A and B, a power supply control means 3, an in-host power supply managing means 2 and an input means 1. The power supply control means 3 is provided with a state of device power managing table 4 provided with each sharing state of the group of devices 6 and each power supply state of the group of devices 6 by each host and a system combining state managing table 5 managing the combining state of the systems. Thus, a power control instruction is executed to each device, the state of device power managing table 4 is updated when the power state of the device changes, the system combining state managing table 5 is updated when the combining state of the hosts changes, the power control of the device is required to the power supply control means 3 and the operator given instruction from the file and the console of the input means 1 to the in-host power supply managing means 2.</p> |
