Abstract

A method and apparatus for enhancing data recovery in data processing systems in which applications span multiple logical devices. A data processing system includes multiple standard devices (40-42) for storing data and corresponding BCV devices (43-45) for, in one mode, operating as mirrors of those standard devices. If certain of those BCV devices (43-45) are associated with the same data set, a consistent split operation controls the way in which each of these BCV devices (43-45) is detached from its corresponding standard device (40-42) and made available to another application. Each command to an application for controlling the BCV devices (43-45) is translated into one or more request data structures that identify the BCV devices as being involved in a consistent split operation and that establishes a system lock out for those particular devices during which those devices are split from their respective devices in a consistent manner.
