摘要： With respect to each head mounted on a hard disk, an area accessed by the head is obtained in advance and managed as disk information. Then, if a read error or a write error has occurred during operation, the corresponding head is identified on the basis of a logical block address at which the error has occurred. If a read error or a write error caused by the identified head has occurred multiple times, only data stored in an area accessed by the head is transferred to another hard disk. After the completion of the data transfer, the hard disk with the failed head and the other hard disk serving as the destination of the data transfer are used as hard disks constituting the same RAID array.
摘要翻译：对于安装在硬盘上的每个头部，由头部访问的区域预先获得并作为磁盘信息进行管理。然后，如果在操作期间发生读取错误或写入错误，则基于发生错误的逻辑块地址来识别对应的头部。如果由识别的头部引起的读取错误或写入错误发生多次，则只有存储在头部访问的区域中的数据才被传送到另一个硬盘。数据传输完成后，将作为数据传输目的地的故障磁头和其他硬盘的硬盘用作构成相同RAID阵列的硬盘。

摘要： A storage system in which a storage control apparatus writes data in each of divided areas defined by division of one or more storage areas in one or more storage devices, after encryption of the data with an encryption key unique to each divided area. When the storage control apparatus receives, from a management apparatus, designation of one or more of the divided areas allocated as one or more physical storage areas for a virtual storage area to be invalidated and an instruction to invalidate data stored in the one or more of the divided areas, the storage control apparatus invalidates one or more encryption keys associated with the designated one or more of the divided areas. In addition, the storage control apparatus may further overwrite at least part of the designated one or more of the divided areas with initialization data for data erasion.
摘要翻译：一种存储系统，其中，存储控制装置在通过对每个分割区域唯一的加密密钥加密数据之后，在一个或多个存储装置中的一个或多个存储区域的划分中分割的每个划分区域中写入数据。当存储控制装置从管理装置接收被分配为要被无效的虚拟存储区域的一个或多个物理存储区域的划分区域中的一个或多个的指定，以及使存储在所述一个或多个分割区域，存储控制装置使与指定的一个或多个分割区域相关联的一个或多个加密密钥无效。此外，存储控制装置还可以用用于数据擦除的初始化数据来覆盖指定的一个或多个划分区域的至少一部分。

摘要： A data transfer method transfers data stored in a first storage part to a second storage part within a storage apparatus. All data stored in units of data regions within the first storage part are transferred to the second storage part, and with respect to each data region for which a data transfer is unsuccessful, redundant data are transferred to the second storage part from a third storage part which stores the redundant data identical to the data stored in the first storage part.

摘要： In a storage system, a disk device performs recovery and transfers read data to a control device, and the control device judges the validity of the recovery to prevent a transfer of erroneous data. A control device read-accesses a disk device, and the disk device returns read data and a recovered read error response. A control device, at the time of an initial recovered read error, performs a retry of a similar command, and if an error does not occur for read commands including the retry read command, judges the data to be valid. Uncertain data (suspect data) upon occurrence of a recovered read error is restored through disk retry, and accurate read data can be transferred to the host.
