摘要： When receiving a notification of an error detected by patrol processing of the device adaptor for a secondary disk apparatus, a first recovery processing unit reads out data corresponding to the error location from a normal primary disk apparatus and writes the data into the error disk apparatus to eliminate the error. If it is determined that the content of the error notification is abnormality of the block ID which is an identifier of the order of writing data, a second recovery processing unit retrieves a correct write address indicated by the identifier, compares data of the error disk apparatus with that of the normal disk apparatus, determines that a lost write exists in the case of mismatch, and eliminates the lost write by writing the data read out from the normal disk apparatus into the error disk apparatus.
摘要翻译：当接收到对辅助盘装置的设备适配器的巡检处理检测到的错误的通知时，第一恢复处理单元从正常主盘装置中读出与错误位置对应的数据，并将该数据写入错误盘装置消除错误。如果确定错误通知的内容是作为写入数据顺序的标识符的块ID的异常，则第二恢复处理单元检索由标识符指示的正确的写入地址，比较错误盘装置的数据与通常的盘装置的情况相同，判定在不匹配的情况下存在丢失的写入，并且通过将从普通盘装置读出的数据写入错误盘装置来消除丢失的写入。

摘要： Even if failure, or the like, occurs during the encryption process, the encryption process is surely resumed. A flag changing unit changes an encryption flag of one disk to being encrypted after an encryption request is received and before the encryption of the data stored on the one disk is started. The flag changing unit changes the encryption flag of the one disk to having been encrypted and changes the encryption flag of the other disk to being encrypted before copying the encrypted data from the one disk to the other disk is started. The flag changing unit changes the encryption flag of the other disk to having been encrypted after copying to the other disk is completed.

摘要： A storage system has a plurality of disk storage devices and a controller for controlling the plurality of disk storage devices, and diagnosis of a write miss to a disk of the disk storage device. The controller for controlling the plurality of disk storage devices attaches an ID to write data, and after write access to the disk drive, the controller reads the write data from the disk drive, and compares the ID of the read data and the attached ID. The controller updates the ID for each write command. Therefore the old write data and the new write data can be identified, accurate diagnosis is possible, and the failure of an individual disk drive can be detected immediately.

摘要： A device adaptor that controls a disk, wherein a storage area is divided into a plurality of blocks, detects a block that includes a read error. Next, the device adaptor detects a write omission in blocks that are within a predetermined range from the block that includes the read error. To be specific, the device adaptor reads data from the blocks that are in the vicinity of the block that includes the unrecovered read error in a suspect disk. Next, the device adaptor reads from a redundant disk, data of a block that corresponds to the block that includes the unrecovered read error (data of block “B” in an example shown in FIG. 1) and compares the read data to the data read from the suspect disk to detect the write omission.
