I use a sequence of:
dump 0uBf 2097152 /dev/nrst0 /
dump 0uBf 2097152 /dev/nrst0 /usr
dump 0uBf 2097152 /dev/nrst0 /u
[ ... ]
mt -f /dev/nrst0 rewind
which seems to work fine. Yes, I have restored from one of these
tapes, and I verify each and every tape I dump.
fyi: the 2097152 number is roughly 2Gb's worth of 1Kb blocks;
when putting multiple dumps on one tape it's arbitrary,
since dump ought to detect EOT if you get that far.
Good luck,
dave
