Abstract:
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.
