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.

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*

estimated 24870 tape blocks on 0 tape(s)

*no space on dev 6/0*
no space on dev 6/0

Thanks,
Ken
