​GPT partitioned disks will have device nodes like da0p1 (meaning partition
1).

MBR partitioned disks will have device nodes like da0s1d (meaning
partitiong d in slice 1).

You can use "gpart show da0" to get more information.

IOW, you have MBR partitioned disks, and should not use the suggested
command as it only applies to GPT partitioned disks.
