Storage control system and storage control method

A storage control method, comprising:

• reading a data set from a storage apparatus if necessary in response to an I/O (Input/Output) request;
• performing an all-type address check which is a check to determine whether one of a first address and second address which correspond to a read-target data set in address translation information, which is information indicating a mapping relationship between one or more first addresses and one or more second addresses, matches the address among the data and address contained in the data set,
• the one or more first addresses each being an address which belongs to the first address type, and
• the one or more second addresses each being an address which belongs to the second address type;
• and
• performing processing according to the I/O request when the result of the all-type address check is true.

A computer program which causes a computer to:

• read a data set from a storage apparatus if necessary in response to an I/O (Input/Output) request;
• perform an all-type address check which is a check to determine whether one of a first address and second address which correspond to a read-target data set in address translation information, which is information indicating a mapping relationship between one or more first addresses and one or more second addresses, matches the address among the data and address contained in the data set,
• the one or more first addresses each being an address which belongs to the first address type, and
• the one or more second addresses each being an address which belongs to the second address type;
• and
• perform processing according to the I/O request when the result of the all-type address check is true.
