ABSTRACT:
A system, method, and computer program product in a data processing system for increasing data storage performance. The data processing system includes multiple primary storage devices and a spare storage device. A logical volume definition is established that defines logical volumes utilizing the primary storage devices. A failure of one of the primary storage devices is detected. Data that was stored on the failed primary storage device at the time the failure was detected is constructed on the spare storage device. The spare storage device is then assigned in the logical volume definition such that the spare storage device becomes a primary storage device. The reference to the failed primary storage device is removed from the logical volume definition.
