Abstract: A storage apparatus in which at least a first storage medium and a second storage medium are installable and only the first storage medium is initially installed, the storage apparatus including a redundancy unit for executing a redundancy operation in which the same data is stored in both of the installed first storage medium and the second storage medium, and a controller for controlling the redundancy unit so that the redundancy unit can execute a restricted operation in which data is stored only in the first storage medium, until the second storage medium has been installed. The controller controls the redundancy unit so that the redundancy unit can return from the restricted operation to the redundancy operation after the second storage medium has been installed.
