We've just added DS14mkII shelves on the fly. The only catch for us was using ESH2 modules, you have to have the right version of ontap, or it panics the filer when you open the loop. And yes, once you have the propper requirements it's as simple as flipping the terminator. The drives are seen in 30 seconds or so. (FAS940 cluster)

I'm not clear what you doing here, are you saying that you already have shelves on the new controllers and you want to add shelves into the loop in real time? If the controllers are completely unused, just cable them up and turn on the termination switches to the correct positions, _then_ I'd run the 'storage enable adapter' command.
To me, you don't want to enable the storage until all the hookups are done and correct. Once you do the enable command, it will go out and probe that adapter, so it should be physically all setup ahead of time.
But hey, I'm ignorant and I'd love to be educated here too.
