Abstract
An information processing system includes: CPUs; storage devices; switches; dummy storage devices which are with respective storage devices and each of which sends, when receiving an identifying information request, its own identifying information back to a sender of the identifying information request; and dummy CPUs which are associated with respective CPUs and each of which tries to, when receiving an instruction for acquiring identifying information from a dummy storage device, acquire the identifying information of the dummy storage device by transmitting the identifying information request, and sends the identifying information as response information back to a sender device of the acquiring instruction.
