I don't think there is a 1:1 correspondence that is stable across reboots (e.g. when I had two external HDs they sometimes switched places between da8 and da9 – which is why you should use sernos as much as possible). You can look at the minor and major device numbers though: % ls -l /dev/da* /dev/serno/WMAVU2232228____* crw-r----- 1 root operator 31, 0x1e110047 Nov 24 17:00 /dev/da8 crw-r----- 1 root operator 31, 0x1e120047 Nov 24 17:20 /dev/da8s1 crw-r----- 1 root operator 31, 0x1e110047 Nov 24 17:00 /dev/serno/WMAVU2232228____ crw-r----- 1 root operator 31, 0x1e120047 Nov 24 17:20 /dev/serno/WMAVU2232228____.s1 with matching devices they will be the same. //matthiasr
