Okay. I know I was messing with that parameter on one of these machines, I though I'd tried it on this one. But, maybe that was the older box with the HBA in it. While I try that, I have a question. I understood that tunable to be a way to get the mfi(4) driver to allow the mrsas(4) driver to be used for devices they both would recognize. But, in this case, it's clear that the mfi(4) driver has now knowledge of this device. Is that tunable being set necessary to have the mrsas(4) driver even find the devices it knows how to support that mfi(4) doesn't? If so, that's a very unfortunate situation. Because there will be a significant set of controllers, like the one I have in this system, that totally fail to present themselves when installing from the install media. Maybe this is a political issue, and I should stop thinking about it, but. Let me know if I'm understanding the technical side, that there are cards mfi(4) has no support for, but this tunable prevents mrsas(4) from attaching them? - Chris
