That is your tape drive, not the changer.
I'm certain dell does not 'manufacture' tape drives.
Probably manufactured by IBM and put into a dell housing.
My dell lto-1 says HP.

But it is the drive, not the changer.
So mtx is not an appropriate command.
mtx manipulates the changer.
mt would be used to manipulate the drive.
The appropriate device may not be sgX (scsi generic),
but stX (scsi tape).
