I need to sudo cs delete an encrypted hard drive but get an error "Not a valid CoreStorage Logical Volume Group UUID"

Ok so I encrypted an internal HDD with DOE compliant encryption, and forgot the password. I am not using a typical mac bootloader so apple C when its booting will not work to delete it before its mounted. I have to do it through the terminal. The drive I want to delete is HDD2. Here is the screen capture of running diskutil cs list in terminal.

Then I disconnected everything to avoid problems, leaving my encrypted HDD only, copied the UUID, it's in this format:

But I am unsure which group or physical UUID I need to use, there are three associated with HDD2, logical volume group, physical volume and logical volume family. I thought before pressing enter I better ask first ... as I tried it on the physical volume first and I got the error in the title so dont want to start guessing what do to.
