(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) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net /dev/ada11: Unable to detect device type Smartctl: please specify device type with the -d option. Use smartctl -h to get a usage summary $ sudo smartctl -d atacam -i /dev/ada11 smartctl 5.39.1 2010-01-28 r3054 [FreeBSD 8.0-STABLE amd64] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net === START OF INFORMATION SECTION === Model Family: Seagate Barracuda 7200.11 family Device Model: ST31500341AS ... Also, out of curiosity, are you using the ahci(4) driver or the siis(4) driver? Steve Polyack
