I just bought two Dell PE-1950's to use as routers. They have LSI Logic
PERC/5i's attached to 80GB SATA drives. I am pretty sure this is the
same card used for SAS.
One thing is for sure, the mfi(4) card and driver aren't shy! See below
for examples of the kernel messages I get regularly. I am sure drive
failure would be well noted.
As to rebuilding on-line, I suspect a drive (hot-)swap will initiate the
rebuild. There is a CLI tool (megarc) in ports/sysutils/megarc but I
haven't tried to use it yet.
All in all I would recommend the PERC/5i.
So I've just picked up a Dell PE-860, with the SAS card. However it
doesn't appear to be an mfi(4) card, instead it's an mpt(4) card.
And, it doesn't appear to work properly; at least something isn't quite
right.
I've installed 6.2 on the box, and I'm attempting to create a gmirror
with both of the disks attached to the mpt. I've created the filesystem
on one of the disks ok (gmirror boot0 on da1s1), and then I attempt
to insert the second disk (da0s1).
The problem is that the synchronisation appears to progress ok, but
when I add some additional load, like cvsuping the ports collection
at the same time, after a short period I get loads of errors from
the mpt controller and then geom disconnects the drive (da0s1).
Wierdly when I reboot the machine the mpt controller refuses to
probe da0, and I have to physically power cycle the machine before
it sees the drive again.
The error messages from mpt are attached in the file called 'messages'.
The kernel probe boot time log is attached as dmesg.log.
I hope there's a simple fix; I was hoping to commission this machine at
the end of this coming week!!!!

Hey Joe
If you have to power cycle the box for it to work again I'd say the problem
is more than likely hardware related and not something FreeBSD unless the
driver for the card has the ability to disable the drive on the raid
controller which I doubt.
