摘要： A response of a disk device during rebuild can be sped up. A disk array control device determines whether or not there is a normal read request during rebuild. If there is a read request during rebuild, data is read by sequentially switching a plurality of disk devices in a certain block size unit lower than a block size in which each disk device reads data during normal read.
摘要翻译：重建期间磁盘设备的响应可以加快。磁盘阵列控制装置在重建期间确定是否存在正常的读取请求。如果在重建期间存在读取请求，则通过以比每个磁盘设备在正常读取期间读取数据的块大小的某个块大小单位顺序切换多个磁盘设备来读取数据。

摘要： A RAID system performs host I/O processing during RAID formatting of a plurality of physical disk drives. The controller executes sequential format processing and one-point format processing. A RAID format writing size (SFS) for sequential format processing is set larger than a RAID format writing size (OFS) for one-point format processing. Delay of host I/O processing is reduced, so that the time required for RAID formatting can be shortened.

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.
