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.

摘要:
A storage system capable of reducing the start-up time of disk drives is provided. If a power source monitor circuit itself is normal (S93), the power source monitor circuit reads a detection signal from a detection circuit, and checks power sources (S94). If the power sources are normal (S95), all disks are spun up (S96). When the spin-up of all disks is completed (S98), processing is completed. If either of two power sources fails (S95), the power source monitor circuit reports the fact to a host control logical part (S99). The power source monitor circuit clears its internal counter to zero (S100) and issues a drive command to HDDs (S101). When the spin-up of all disks is completed (S103), processing is completed. If there is a disk which has not yet been spun up, the power source monitor circuit sets the internal counter to n+1 (S104) and returns to Step S101. N-number of HDDs are divided into groups respectively including six disks, six disks, four disks and one disk, and if the disks are driven in units of the groups, the power source monitor circuit sets the internal counter to n+Δn.
