The reliability of data access to a storage unit can be improved. A storage system (10) comprises: a plurality of storage apparatuses (18a to 18c) each of which has a storage unit, a first relay unit connected in series to a data transmission path (13) for relaying the data access to the storage unit, and a second relay unit connected in series to a data transmission path (14) and also connected to the first relay unit via a third data transmission path, the opening/closing of which is controlled in accordance with an external instruction, for relaying the data access to the storage unit; and a controller (12) that disables a communication using the third data transmission path of each of the plurality of storage apparatuses (18a to 18c), thereby monitoring the statuses of the connections to the storage unit via the data transmission paths (13, 14) and that, when having detected any storage unit the data access to which cannot be performed via any of the data transmission paths (13, 14), transmits an instruction to enable a communication using the third data transmission path of at least one of the storage apparatuses.
