Wether it is SCSI or SANs LUNS, "sysctl kern.disks" always shows da<no>. it don't distinguish b/w them. and similarly "/usr/local/sbin/smartctl -i da0" also gives results that is acceptable. Although i don't know what is that Serial no in SANs LUN case. ex: [EMAIL PROTECTED] ~]# /usr/local/sbin/smartctl -i da0 smartctl version 5.37 [amd64-portbld-freebsd6.2] Copyright (C) 2002-6 Bruce Allen Home page is http://smartmontools.sourceforge.net/
