ABSTRACT:
Transferring I/O from a first storage device coupled to a storage area network to a second storage device coupled to the storage area network includes blocking I/O operations for a first port of the first storage device coupled to the storage area network, where the first port is associated with a first identifier. Transferring I/O also includes coupling the second storage device to the storage area network via a port associated with a second identifier different from the first identifier, coupling a virtualization engine to the storage area network via a first port provided with the first identifier and via a second port, and causing at least a portion of I/O operations received by the virtualization engine through the first port thereof to be routed through the second port thereof to the second storage device without host/application disruption.
