Looks like you're on the right track - but not quite there - the main thing is to use the device minor to match things up - on my system, for example: # ls -l /dev/ad6s1a crw-r----- 1 root operator 20, 0x00020030 May 29 21:51 /dev/ad6s1a # ls -l /dev/serno |grep 0x00020030 crw-r----- 1 root operator 20, 0x00020030 May 29 21:51 6RY18WCV.s1a # grep 6RY.*s1a /etc/devfs.conf link serno/6RY18WCV.s1a dev02.root # ls -l /dev/ |grep 0x00020030 crw-r----- 1 root operator 20, 0x00020030 May 29 21:51 ad6s1a crw-r----- 1 root operator 20, 0x00020030 May 29 21:51 dev02.root So as can be seen from above, the 'ad6s1a' device is showing up with the device minor of 0x00020030 - which corresponds to '6RY18WCV.s1a' and also, in my case, as I have setup devfs aliases, /dev/dev02.root . Running 'natacontrol list' might also be helpful: # natacontrol list ATA channel 0: Master: no device present Slave: no device present ATA channel 1: Master: acd0 <COMPAQ DVD-ROM LTD163/GQH3> ATA/ATAPI revision 0 Slave: acd1 <CDD4851 CD-R/RW/C2.8> ATA/ATAPI revision 0 ATA channel 2: Master: no device present Slave: no device present ATA channel 3: Master: ad6 <ST3250410AS/3.AAA> Serial ATA v1.0 Slave: no device present Cheers, - Chris
