摘要： Described are techniques used in performing data replication processing. Data is replicated on a recovery site from a production site. When a disaster occurs, the state of the replication processing is determined and a restart copy of the data is made available from the recover site. Processing continues based on whether protection mode is desired such that the system executes using the recovery site as the restart with a replicated copy of the data. Data is propagated from the recovery site to the production site to resume operations and replication processing originating from the production site.

摘要： 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 for storing data and corresponding BCV devices for, in one mode, operating as mirrors of those standard devices. If certain of those BCV devices are associated with the same data set, a CONSISTENT SPLIT operation controls the way in which each of these BCV devices is detached from its corresponding standard device and made available to another application. Each command to an application for controlling the BCV devices 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.

摘要： A data-mirroring method in which, while an I/O process is processing a first I/O request for writing data to a first device, control is obtained from that I/O process executing on a host computer. A second I/O request, this one for writing the data to the second device, is then created. Then, control is returned to the I/O process by causing the first I/O request to be made available to a first data storage system managing the first device.
