I had actually read through just about every Google hit on ataraid pertaining to FreeBSD (and many others that were not) before I first posted, so I just realized the key piece of information that I have been neglecting to include: When I boot 5.2(.1) from the ISOs, I am able to see -only- the ad4 and ad6 separate drive components of the RAID1 array, and not the actual RAID1 array itself (as ar*). I'm using the standard sysconfig install, and going into the Custom Expert mode, I am only given the option to select ad4 and ad6 during the partitionable device selection, so I'm assuming (?) that there's something else I need to do in the background or prior to loading sysconfig in order to have sysconfig see the RAID1 array itself? I've heard "use 'device ataraid'" from this forum, but no real clear directions on how to use it (again, I did a search on this as well), but I've also heard "it works out of the box" which seems to be in conflict with the former statement (like most good assertions we know). Sadly, it appears to not be working "out of the box" for me with 5.2 or 5.2.1; whereas 5.1 with the kernel load module from the vendor DID work. I know how it should look...so am I going back to using 5.1 or...? Thanks again, --Sean Goodman
