摘要： PROBLEM TO BE SOLVED: To provide a RAID controller which migrates only a data area being accessed by a head which has detected abnormalities to a spare disk, if the abnormalities are resulting from a specific head, and to provide a RAID device.
SOLUTION: The RAID controller acquires in advance and manages disk information on areas to which each head of mounting heads of a hard disk accesses. At operation time and when a read error or a write error occurs, the target head is specified based on the logical block where the error has occurred. When read errors or write errors depending on a specific head occur multiple times, only the stored data of the area to which the head concerned accesses are migrated to the other hard disk. Starting from data migration point, a hard disk of head fault and the other hard disk of data migration destination are operated as a hard disk constituting the same RAID.

摘要翻译：要解决的问题：提供一种RAID控制器，其仅将由检测到异常的头部访问的数据区域迁移到备用盘，如果异常是由特定头部产生的，并且提供RAID设备。
解决方案：RAID控制器提前获取磁盘信息，并管理硬盘安装头的每个磁头访问的区域。在操作时，当发生读错误或写入错误时，根据发生错误的逻辑块指定目标头。当根据特定头发生读取错误或写入错误发生多次时，只有存储的头部相关访问区域的存储数据才会迁移到另一个硬盘。从数据迁移点开始，头部故障的硬盘和数据迁移目的地的另一个硬盘作为构成同一RAID的硬盘进行操作。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To prevent erroneous data transfer by determining the validity of recovery in a storage system wherein a disk device recovers and transfers read data.
SOLUTION: A control device performs read access to the disk device 15, and the disk device 15 returns read data and a recovered read error response. The control device 10 carries out retry by the same command at the first recovered read error and determines the data to be correct when no error occurs, to a read command including the retry. Uncertain data (faked data) at the occurrence of the recovered read error is recovered by the retry of the disk, and correct read data can be transferred to a host.

摘要： PROBLEM TO BE SOLVED: To shift the performance of a whole storage device to the optimal state by replacing a spare storage means which is satisfactory in performance and a storage means under operation.
SOLUTION: An evaluation means 11a evaluates the performance of a data storage means 12a and a spare storage means 12b. A comparator means 11b compares the evaluation of the data storage means 12a with the evaluation of the spare storage means 12b, and determines the superiority or inferiority of the data storage means 12a and the spare storage means 12b. When the data storage means 12a is inferior to the spare storage means 12b based on the superiority or inferiority of the data storage means 12a and the spare storage means 12b determined by the comparison means 11b, an allocation means 11c assigns the spare storage means 12b to the data storage means, and assigns the data storage means 12a to the spare storage means based on the speriority or inferiority determined by the comparison means 11b.
