| 20080263393 | STORAGE CONTROLLER AND STORAGE CONTROL METHOD - 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. | 10-23-2008 |
| 20090292945 | DISK ARRAY APPARATUS AND METHOD FOR CONTROLLING THE SAME - A disk array apparatus capable of reducing a disk drive fault rate where a time-out failure has occurred. The disk array apparatus includes a plurality of disk drives, and a control unit for performing data input/output processing of the disk drives in response to a data input/output request from a host system. The control unit includes: a memory for storing control information for specifying a failure of at least one of the disk drives, and failure information of the faulty disk drive, a circuit for specifying, from the failure information, the disk drive in which a time-out failure has occurred, and issuing an instruction to retry a control command to the disk drive, and a circuit for outputting a control signal to the faulty disk drive in order to hard reset the disk drive if the disk drive does not recover from the failure. | 11-26-2009 |

| 20080211439 | DRIVE DEVICE FOR A BRUSHLESS MOTOR - A drive device for a brushless motor executes an abnormality diagnosis (disconnection/short-circuit) of a motor side circuit. In detecting abnormality of the motor side circuit, the drive device includes a terminal voltage monitor circuit that monitors a terminal voltage of an output terminal that is connected to a motor terminal of respective phases. A microcomputer starts abnormality diagnosis under a condition where the motor is stopped, and an object to be driven has normally operated at the time of driving the motor. For executing the abnormality diagnosis, the microcomputer turns on/off only a transistor of the drive circuit of one phase in a state where all of transistors are turned off, and acquires monitor signals to execute the abnormality diagnosis based on signal levels of the monitor signals. | 09-04-2008 |
