Re: Dell CERC SATA 2S question -- software RAID instead?
-- quoting Jonathan Reeder -- Since the SATA RAID controller in the Dell PE SC420 isn't supported yet, is there anything I can do with atacontrol to run my two drives as a software RAID instead of relying on the controller? I've never used SATA before, so any advice anyone can offer is greatly appreciated. If you're using FreeBSD 5.3 than you should take a look at man gmirror. This could be what you want. I am using it w/o any problems so far... HTH! Greetings, Matthias -- And remember not to act afraid. Animals can smell fear.

-- quoting Jonathan Reeder -- Hmm, well since I'm stuck with the hardware that I've been given, does that mean that I need to pursue a different OS? I'd love to run FreeBSD on this server, but I can't change any of its hardware so do I need to look at Linux? I am not a FreeBSD guru, but if your hardware isn't supported by FreeBSD and you are not interested in code hacking then I am afraid you have no other choice then chaning OS :( -- Lisa: So gambling makes a good thing even better?

AFAIK you cant use software RAID on your system drives as the system has to boot before software RAID can be loaded. Thus you would need a dedicated system drive which the system can boot from in order to load software raid on the other two disks. This is probably not what you want. Roger O.

Dell CERC SATA 2S question
I just got a Dell PowerEdge SC420 (or something like that) with the CERC SATA 2S RAID. When the server boots, the Adaptec utility tells me that I have one array configured, a RAID 1 with 2 drives. However, when I launch the 5.3 installer and go to Allocate Disk Space options, it sees two drives rather than the single RAID array. The two drives it sees are ad4 and ad6. I get an error when I select either of them, saying: A geometry of 310019/16/63 for ad(4|6) is incorrect. Using a more likely geometry... Any thoughts on how I can get FreeBSD to see my SATA array as an array rather than as two separate drives? Thanks a bunch.
