    • 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.
    • 本发明的存储控制系统可以使用冗余配置的访问信道来执行存储设备的设置。 存储控制系统的控制器可以使用系统A和系统B的多个存取通道访问存储设备。各个I / F控制单元各自包括多个常开型开关。 系统A的开关和系统B的开关分别与线或线连接。 盘控制单元根据设定表将控制信号输出到I / F控制单元。 当在系统A的I / F控制单元发生故障时,各开关的输出信号转移到高阻抗状态。 因此,可以通过从系统B的I / F控制单元输出与期望的操作模式和识别信息对应的信号来设置存储装置。
