摘要： A disk array controller detects disk drive power-on-reset events that may cause a disk drive to lose uncommitted write data stored in its cache. When an unexpected disk drive power-on-reset event is detected, the disk array controller may initiate an appropriate corrective action. For example, the disk array controller may initiate a disk drive rebuild operation, or may re-send a set of write commands to the disk drive.

摘要： A disk array controller reliably detects disk drive power-on-reset events that may cause a disk drive that has uncommitted write data stored in its cache to lose such data. The methods for detecting the power-on-reset events include operating the disk drives in an ATA security mode in which a power-on-reset of a disk drive will cause the drive to enter a locked state in which data transfer commands are aborted; and tracking power cycle count attributes of the disk drives over time. When a disk drive power-on-reset event is detected, the disk array may be efficiently restored to an operational state by re-executing or “replaying” a set of write commands that are cached within the disk array controller. The invention is also applicable to single-disk-drive storage systems.
摘要翻译：磁盘阵列控制器可靠地检测可能导致存储在其高速缓存中的未提交写入数据的磁盘驱动器的磁盘驱动器上电复位事件丢失此类数据。用于检测上电复位事件的方法包括以ATA安全模式操作磁盘驱动器，其中磁盘驱动器的上电复位将导致驱动器进入数据传输命令被中止的锁定状态; 以及随着时间的推移跟踪磁盘驱动器的功率循环计数属性。当检测到磁盘驱动器上电复位事件时，可以通过重新执行或重播在盘阵列控制器中缓存的一组写入命令来将磁盘阵列有效地还原到操作状态。本发明也适用于单盘驱动器存储系统。
