摘要:
A storage system includes a plurality of disk drives, one or more controller boards for controlling data read and write from/to the plurality of the disk drives, and a Fibre Channel switching board for controlling path switching between the controller boards and the plurality of the disk drives. The Fibre Channel switching board has a control logical circuit for adjusting a control signal system between the controller boards and the disk drives according to a connection confirmation signal indicating whether or not the control signal cable is connected to the Fibre Channel switching board.

In a RAID system, the power supplied to hard disks (HDDs) can be increased, and a plurality of types of HDDs can be installed. A plurality of HDD packs 33 are supplied with a single high voltage from a motherboard 28. The HDD packs 33 each accommodate, in a canister, an HDD 107, 181, 185 or 187 with different power supply specifications or communication interface specifications, as well as a DC/DC converter 109 to convert the power supply. Part of the HDD packs 33 have a data transfer interface conversion circuit 195 as well.

The storage control device of the present invention detects faults on the disk drives at an early stage, thus enhancing convenience of use. The disk drives are switchingly connected to a subordinate communication control unit via a switching circuit. An error information collection unit of an error monitoring unit detects errors which have occurred at each port of the switching circuit. The errors which have been detected are stored in an intermediate storage unit, and are input via an error information notification unit to a fault recovery control unit of the subordinate communication control unit. By doing this, it is possible to immediately specify whether or not a fault has occurred on any of the disk drives, and to start a fault recovery procedure.
