PROBLEM TO BE SOLVED: To provide an information device that is able to accurately start as a server device having the same information as an active system while restraining a workload required for switching.SOLUTION: An information device comprises start signal detection means 1, communication means 2, and control means 3. The start signal detection means 1 detects a start signal. When the start signal detection means 1 detects a start signal, the communication means 2 requests second identification information allocated to the information device as a virtual identifier from a prescribed management device, and receives second identification information transmitted by the prescribed management device as a response to the request. The control means 3 operates the information device as a device with the second identification information received from the prescribed management device instead of the first identification information preset to the information device.SELECTED DRAWING: Figure 1 |
