Abstract
A secondary storage controller receives metadata that uniquely identifies a source volume of a primary storage controller. Data stored in the source volume of the primary storage controller is synchronously copied to a target volume of the secondary storage controller. The secondary storage controller receives a command from a primary host to write selected data to the source volume. In response to receiving the command at the secondary storage controller, the selected data is written to the target volume of the secondary storage controller.
