Abstract
A method and apparatus for reducing the bring-up time upon a transfer of control. This is accomplished by performing the physical level access bring-up prior to fail-over or other transfer, on the devices which are only secondarily controlled by the controller. The media level access is performed only by the controller with primary control of the devices. Upon a failure or transfer by the first controller, a media level access can be immediately performed by the second controller without doing a physical level access first, since this had been done prior to the fail-over or transfer.
