摘要：
[This invention] inhibits the response time of the storage control apparatus from being longer even if the response time of the storage apparatus is long.The disk adapter (DKA), receiving a read message from the channel adapter (CHA), sets the timeout time in accordance with specified conditions, and tries to read data from the storage apparatus 4. As the timeout time, either the normal value or the shortened value is selected. If a timeout error occurs, the read job is reset, and correction read is started.
