My guess (just a guess, but as a former support tech for RAID controllers it's an educated guess) is that what you see will depend on whose controller it is and which version of firmware is in it. I would expect Adaptec, pretty much all versions, to throw an error and make you, the operator, decide. I would expect LSI to have different behaviors depending on who the OEM customer was (i.e., Intel, Dell etc.). And I would expect the el cheapo controllers to just make a mess. We had to actually do this kind of stuff in our lab to see what would happen when I was working for Intel (who used both Adaptec and LSI controllers in their products) because we had customers that did the dumbest stuff you can imagine (and a lot that you can't imagine). But it was a long time ago and I just don't remember now. Not that any of it would be the same now anyway. I would be interested in seeing the results of any and all experiments.
