摘要： Spare disk drives are provided to a chassis for storing storage devices, and, when any one of the storage devices configuring RAID fails, the storage controller copies data of the failed storage device to a spare storage device, and recognizes an additional storage device inserted into the spare disk drive as the spare storage device. Thereafter, when the foregoing storage device fails, the storage controller reproduces data of the failed storage device, copies this data to an additional storage device inserted into the spare disk drive, and recognizes the additional storage device inserted into the spare disk drive as a spare storage device. Subsequently, when the foregoing storage device fails, the storage controller reproduces data of the failed storage device and copies this data to an additional storage device inserted into the spare disk drive. RAID 6 is maintained thereby.

摘要： Times at which requests for a data read or data write from/to a logical volume are received are stored in memory as access times of a RAID group making up the logical volume. When a predetermined time has elapsed after the access time, a number of the hard disk drives according to the redundancy of the RAID group are set to a power saving mode. Assume there are first hard disk drives and second hard disk drives having shorter lifes and the RAID group exceeds a predetermined time after the access time. When the RAID group consists of only the first drives, a number of the first drives according to the redundancy of the RAID group are set to a power saving mode and when it consists of only the second drives, an arbitrary number of second drives are set to a power saving mode.

摘要： A diskarray system has a diskarray controller and a plurality of disk devices. Each of the disk devices has a media, a head, and a head position controller. The diskarray controller performs online data check operation, and stops the online data check operation over the disk device at first predetermined timing. After stopping the online data check operation, the diskarray controller issues an unload enable command to the disk device so as to move the head to a position different from positions at which the head reads or writes data from or to the media. The head position controller of the disk device moves the position of the head on the basis of the received unload enable command.

摘要： A disk array system having first and second housings and a controller for controlling the first and second housings. Fiber channel hard disk drives are received in the first housing, and serial ATA hard disk drives are received in the second housing. When reading data stored in a serial ATA hard disk drive in the second housing, the controller reads a plurality of pieces of data including the data to be read and parity data for the plurality of pieces of data from all the hard disk drives of an RAID group to which the hard disk drive storing the data to be read belongs. Thus, the controller examines whether the plurality of pieces of data including the data to be read are written in the hard disk drives with erroneous contents or not.

摘要： The present invention manages disk-drive types in a storage device in which a mixture of disk drives of a plurality of types with different interfaces is stored. The storage device enclosure stores a mixture of an FC disk drive 220F with a fiber channel interface and a SATA disk drive with a serial interface. The SATA disk drive is connected to a fiber channel via an FC/SATA interface connection device 233 that performs interface conversion. At startup and so forth, the controller 310 issues an inquiry to the enclosure management unit or to each of the disk drives and, based on the address allocated to each of the disk drives, or similar, automatically confirms the type of each disk drive and manages the confirmation results.
