A storage unit (211, 613) stores management information (621, 622) where identification information of each of a plurality of devices (512-1 to 512-N) used by an information processing apparatus (414-1 to 414-4), first positional information, and second positional information are associated with one another. The first positional information indicates a position of a device storage (415-1 to 415-4) storing the plurality of devices. The second positional information indicates a storage position of each of the plurality of devices in the device storage. An identification unit (212, 611) receives failed device information including identification information of a failed device among the plurality of devices from the information processing apparatus. The identification unit identifies the position of the device storage storing the failed device and a storage position of the failed device in the device storage from the identification information of the failed device included in the failed device information on the basis of the management information.
