Abstract
A storage control apparatus receives a write request for a storage apparatus. When the storage control apparatus receives the write request, the storage control apparatus duplicates into a specific storage area, data stored in a storage area of the storage apparatus and parity data whose generation source is the data. The storage control apparatus determines whether one of the storage apparatuses is started up for which a writing process is executed in response to the write request. When the storage apparatus is re-started, the storage control apparatus writes the data duplicated in the specific storage area into the storage area of the duplication source of the storage apparatus and writes the parity data duplicated in the specific storage area into the storage area of the duplication source of the storage apparatus.
