Interesting to see in how many differents ways you can use the
term "label". BTW I have no idea what an "OTP serial number" is.

You see that there? You should find this symlink on your system:
/dev/disk/by-id/… …GST02TBG221146
pointing at some random /dev/sdX. Where you put /dev/sdX,
put /dev/disk/by-id/… …GST02TBG221146 instead. Then you'll
know you're referring to that disk. Likewise the others.
