running procs with rmt0 in them include....

sbdevice /dev/rmt0
/bin/ksh /usr/sbin/readsbheader -Nd -f/dev/rmt0 -l

can I kill these safely?

first you should issue
fuser -u /dev/rmt0
to check which process(es) actually uses the device.
sbdevice is used to process tape devices inside the sysback context, readsbheader displays the header label of any sysback backup.
It seems that you tried to read the tape header including a backup listing, which came never to an end, for what reasons ever.
-d and -l can produce very long listings, maybe someone lost patience and closed his/her shell before the report cam to an end?
Anyway, yes, I'm fairly sure that you can kill those processes safely, as with "readsbheader" a tape  is only read and never written.
