ABSTRACT:
A method for automatic peer to peer address switching, comprising: defining a secondary device as a logical alias of a primary device and performing the following steps concurrently for the primary-secondary device pair upon a determination that address switching is desired: terminating the device pair binding, terminating all logical alias bindings to the first device except the logical alias binding of the primary device to the secondary device, preventing the primary device from receiving I/O requests, and allowing the secondary device to receive I/O requests.
