I see from this thread: http://lists.freebsd.org/pipermail/freebsd-stable/2008-January/039675.html That the PERC 6/i RAID controller seems to work fine with the mfi(4) driver; I was planning on a 4 x 73GB RAID5 setup, so the problems about addressing > 1TB don't seem to apply. My straightforward question is just wondering about how you get diagnostics from this device. My server will be in a remote location, so I'm curious how I would even know if a disk has failed. There wasn't anything about this in the mfi(4) manpage, nor in the RAID section of the Handbook. My current server is in a 2 x 18GB RAID1 setup, but I pretty much plugged it in and it Just Worked, and I never thought about it any more; this time I'd like to know more about how to manage it. Thanks. Jesse Sheidlower
