Andrew, et al.,

completely did not go over well. Or is that what the question meant?

We purposely limited controller support in hpsa to try and prevent problems
in the field. What's needed to get hpsa accepted? Add support for all
hardware?

While we do not want to maintain 2 drivers indefinitely we (HP) must
continue to support cciss for some years to come.

Any guidance is appreciated.
