.... since all the drives, cables and controllers are identical, I'm trying to
figure out if there is something *else* I should be looking into for why smart
would have an issue, but the rest of the OS has no issues with these drives.
(zfs is storing data, reports them all as online, etc). I looked into the
smartctl code, and there definitely is a carve out for FreeBSD 8.1 or later,
but I don't know enough about the new internals to know if the is any kind of
concern parsing more than 10 drives, etc.
DJ,
I have a similar setup with a fair amount of drives on a few Sil3124
controllers and port multipliers. I can't speak for why smartctl cannot
automatically detect the device type, but if you specify '-d atacam',
then it will work just fine:
$ sudo smartctl -i /dev/ada11
smartctl 5.39.1 2010-01-28 r3054 [FreeBSD 8.0-STABLE amd64] (local build)

Also, out of curiosity, are you using the ahci(4) driver or the siis(4)
driver?
