Abstract
A storage control system of the present invention can carry out settings for a storage device using redundantly configured access channels. A controller of the storage control system can access a storage device using a plurality of access channels of system A and system B. Respective I/F control units each comprise a plurality of normally open-type switches. The switches of system A and the switches of system B are respectively wired-OR connected. A disk control unit outputs a control signal to an I/F control unit on the basis of a setting table. When a failure occurs in an I/F control unit of system A, the output signals of the respective switches transfer to a high-impedance state. Therefore, a storage device can be set by outputting, from an I/F control unit of system B, a signal corresponding to a desired operational mode and identification information.
