FAS8020 HA Pair. Multi-path enabled. 8.2.4P4 7-Mode.

I've non-disruptively hot added a shelf before. Can I do the same thing with 2 new shelves at once?

i.e. Connect 2 new shelves together properly, then connect Side A (which will give 1 path to both new shelves at the same time). then connect Side B (which will give the 2nd path to both new shelves at once).

Or do I have to do it as if I was only adding 1 shelf at a time.. ie Completely connect new shelf 1 and then completely connect new shelf 2?

This assumes all s/w and h/w compatibility specs have been met.

Thanks.
