[TUHS] Unix v7 tape drive question

Hi, I am trying to use the 'dump' program but it references rmt1. My system only has rmt0. I have been unable to find how to create this device. I have looked over the reference material but it only references rmt0. Is there any way to redirect a dump to use rmt0? Any help is appreciated. # ls -l total 4 drwxr-xr-x 2 root 336 Mar 1 16:56 . drwxr-xr-x 8 root 288 Feb 21 17:18 .. crw--w--w- 1 root 0, 0 Mar 2 07:47 console crw-r--r-- 1 bin 8, 1 Jan 10 1979 kmem -rw-rw-r-- 1 bin 775 Jan 10 1979 makefile crw-r--r-- 1 bin 8, 0 Jan 10 1979 mem *brw-rw-rw- 1 root 3, 0 Mar 1 20:42 mt0* crw-rw-rw- 1 root 12,128 Dec 31 1969 nrmt0 crw-rw-rw- 1 bin 8, 2 Dec 31 1969 null *crw-rw-rw- 1 root 12, 0 Feb 23 15:55 rmt0* brw-r--r-- 1 root 6, 0 Mar 2 07:47 rp0 brw-r--r-- 1 root 6, 15 Dec 31 1969 rp3 crw-r--r-- 1 root 14, 0 Dec 31 1969 rrp0 crw-r--r-- 1 root 14, 15 Dec 31 1969 rrp3 brw-r--r-- 1 root 6, 1 Dec 31 1969 swap crw-rw-rw- 1 bin 17, 0 Mar 1 19:39 tty crw--w--w- 1 root 3, 0 Mar 1 19:41 tty00 crw--w--w- 1 root 3, 1 Feb 23 16:47 tty01 crw--w--w- 1 root 3, 2 Feb 21 16:56 tty02 crw--w--w- 1 root 3, 3 Feb 21 16:56 tty03 Not only that but when attempting to use dump it creates a file and consumes all the space on rp0 In dev it creates: -rw-rw-r-- 1 root 174080 Mar 2 09:20 rmt1 Sample run: # dump date = Thu Mar 2 09:20:16 2023 dump date = the epoch dumping /dev/rrp3 to */dev/rmt1* I II estimated 24870 tape blocks on 0 tape(s) III IV *no space on dev 6/0* no space on dev 6/0 no space on dev 6/0 no space on dev 6/0 Thanks, Ken -- WWL 📚
