ABSTRACT:
In a network regulated so that the unique identification information for a basic storage apparatus and that of each of a plurality of additional storage apparatuses do not overlap, the storage apparatuses can be connected to the network without being assigned unique identification information. The basic storage apparatus judges, when an additional storage apparatus is powered-on, whether or not an initial value is set in an identification information setting unit in the additional storage apparatus, the identification information setting unit being where unique identification information in the network is set. If it is judged that an initial value is set in the identification information setting unit, the basic storage apparatus enters a first mode in which it creates unique identification information, replaces the initial value with the created identification information, and recognizes the created identification information as unique identification information in the network. If it is judged that a value other than the initial value is set in the identification information setting unit, the basic storage apparatus recognizes that value as unique identification information in the network.
