Hi Thomas, >I just put Dragonfly 3.0.3 on a spare box and at first connected a single USB >HDD to it. After a while I connected two others (of the same type; different >from the first one) and now I found this in dmesg output: > >umass1: <HitachiGST SimpleDrive III by Hitachi, class 0/0, rev 2.00/0.00, addr >2> on uhub6 .. >da9: Serial Number 801130168383 .. >umass2: <HitachiGST SimpleDrive III by Hitachi, class 0/0, rev 2.00/0.00, addr >3> on uhub6 .. >da10: Serial Number 801130168383
Seems like a known problem, please see: http://leaf.dragonflybsd.org/mailarchive/users/2011-09/msg00024.html Where Matt describes problem: >.. >Most USB hard drives run through >a USB<->SATA/Firewire bridge chip and most of these bridge chips can't >handle serial number queries. .. >I don't think there's a good solution for the usb serial number issue >atm, other than to not use USB for any serious hard drive attachments. >For a laptop which only has USB I guess there's no choice, and in that >case you just have to hardwire it to /dev/da8 or something like that. -thomas
