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 code conversion apparatus, a disk drive, a code buffer, and an encryption buffer are included in a storage. The code buffer stores therein first encrypted data present in the disk drive, and the encryption buffer stores therein first unencrypted data present in the disk drive. An encrypting unit encrypts the first unencrypted data present in the encryption buffer to predetermined encrypted data, and a decrypting unit decrypts the first encrypted data present in the code buffer to second unencrypted data. Moreover, a re-encrypting unit decrypts the first encrypted data present in the code buffer to third unencrypted data and encrypts the third unencrypted data to second encrypted data different from the first encrypted data.

摘要： In a disk array system, when a failure occurs in a disk unit under control, a disk controller performs a rebuild process for rebuilding data stored on the faulty disk unit on a spare disk unit (HS). When a rebuild control section accepts an I/O request from a host before completing the rebuild process in all target areas, the rebuild control section specifies a management unit area including a target area of the I/O request and determines whether the rebuild process is completed in the management unit area. If the rebuild process is not completed in the management unit area, the rebuild control section performs the rebuild process in the management unit area by a rebuild process section and rebuilds data on the HS. After that, an I/O request handling section handles the I/O request.
摘要翻译：在磁盘阵列系统中，当在控制的磁盘单元中发生故障时，磁盘控制器执行用于重建存储在备用磁盘单元（HS）上的故障磁盘单元上的数据的重建过程。当重建控制部分在完成所有目标区域内的重建过程之前接受来自主机的I / O请求时，重建控制部分指定包括I / O请求的目标区域的管理单元区域，并确定重建过程是否为在管理单位区完成。如果在管理单元区域中未完成重建过程，则重建控制部分通过重建处理部分在管理单元区域中执行重建处理，并在HS上重建数据。之后，I / O请求处理部分处理I / O请求。

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.
