Unable to wipe a   /dev/nume0n1p   drive.

I have an HP EliteDesk 800 G3 small form factor. It has a solid state hard drive. I need to wipe the hard drive, so I'm using "SystemRescue CD" (it's a Linux distro). I boot from the CD and then I type:    shred -v /dev/sda.
     I've used this method to successfully wipe a previous PC, but on this PC it won't work. On this PC it says "no such file or directory."
     I tried several variations on this command (shred --v.....     shred -verbose.....     shred --verbose.....) but it still won't work.
     So then I typed:   fdisk -l   and I got the following:
          /dev/nume0n1p1
          /dev/nume0n1p2
          /dev/nume0n1p3
          (etc)
     I've never seen this before. I thought I'd see something like:
          /dev/sda1
          /dev/sda2
          /dev/sda3
          etc
     So then I typed:   shred -v /dev/nume0n1p     (as well as the 3 variations of this), but it still won't work.

-Anyone know how I can wipe this PC?
-What is "/nume0n1p"?  Is that the solid state version of "/sda"?
-Are the "v" switch and the "verbose" switch one and the same thing?
-Does it matter if a Linux switch has one dash (-) or two (--)?

I think you have the drive name wrong, The second letter should be v-Victor, not u-Uniform. E.g. on my system
08:26:20$ ls -l /dev/nvme*
crw------- 1 root root 240, 0 Feb 23 10:16 /dev/nvme0
brw-rw---- 1 root disk 259, 0 Feb 23 10:16 /dev/nvme0n1
brw-rw---- 1 root disk 259, 1 Feb 23 10:16 /dev/nvme0n1p1
brw-rw---- 1 root disk 259, 2 Feb 23 10:16 /dev/nvme0n1p2
brw-rw---- 1 root disk 259, 3 Feb 23 10:16 /dev/nvme0n1p3
brw-rw---- 1 root disk 259, 4 Feb 23 10:16 /dev/nvme0n1p4
brw-rw---- 1 root disk 259, 5 Feb 23 10:16 /dev/nvme0n1p5
brw-rw---- 1 root disk 259, 6 Feb 23 10:16 /dev/nvme0n1p6
brw-rw---- 1 root disk 259, 7 Feb 23 10:16 /dev/nvme0n1p7

I thought I needed to wipe this drive because it wouldn't let me image it. It kept giving me some "Task Sequence" error. But now we found out it's not necessary to wipe it.

nobus, it's dawned on me that you're right, manually trying to delete a SSD is kind of strange.

Duncan Roe, you're also right. Those are "v"s and not "u"s (my eyes aren't what they used to be). Thank you for alerting me.

This was my first encounter with SSDs. So far I guess I'm not doing so hot with these. But this was a good learning experience. And noci, thank you for all that information.
