ABSTRACT:
A system and method for automatic failure recovery in a storage system that includes replicating data stored in a first storage volume at a storage system into a second storage volume at the storage system, the first storage volume handling Input/Output (I/O) operations between the storage system and a host device. A failure is detected in the I/O operations with the first storage volume and a recovery process initiated that includes identifying a path from the host device to the second storage volume or a third storage volume to allow continuation of the I/O operations automatically. The third storage volume containing data recovered from the second storage volume.
