Abstract
Techniques for switching between mirrored volumes are described. A system may comprise a multi-path device driver and a processor device, in communication with the multi-path device driver, operable in the computing storage environment. The processor device creates a copy relation identification (ID) between mirrored volumes for using the copy relation ID in conjunction with a multi-path device driver for switching input/output (I/O) for applications between a first path to a second path between the mirrored volumes.
