diskid is disk serial number with "DISK-" prefix
and there is diskinfo(8) command in base system that shows it, too:

# diskinfo -v /dev/ada1 | grep ident
        WD-WMAY04452117 # Disk ident.
# ls /dev/diskid 
DISK-WD-WMAY04452117
# smartctl -a /dev/ada1 | grep Serial
Serial Number:    WD-WMAY0445211
