Zusammenfassung:PROBLEM TO BE SOLVED: To provide a storage control subsystem which facilitates managing access to a logical volume from a host. SOLUTION: The storage control system discriminates whether a data pattern of data to be exchanged (data, hereinafter) with a host device suits any of one or more data patterns not for writing included in prepared information on the data pattern not for writing. When negative discrimination results are obtained, the storage control subsystem stores the data in a logical device formed on a disk type storage device. Alternatively, when affirmative discrimination results are obtained, the storage control subsystem eliminates the data without storing it in the logical device. COPYRIGHT: (C)2011,JPO&INPIT
