I can also add the results of my empirical research since I have an 8200
on site as well. There were no problems using and reusing a single tape
in different modes as long as I did an mt -f /dev/rst9 rew before trying
to use the new density.
I was also able to use the following to approximately double the tape capacity.
8200
dump 0ubsdf 64 10000 54000 - /dev/sd0a | compress | dd of=/dev/nrst1 bs=8b
dd if=/dev/nrst1 bs=8b | uncompress | restore if -
8500
dump 0ubsdf 64 21700 54000 - /dev/sd0a | compress | dd of=/dev/nrst9 bs=8b
dd if=/dev/nrst1 bs=8b | uncompress | restore if -
The 8 blocks with dd was as high as I could go without getting a constant
stream of annoying scsi bus synchronous at 4.0 mbs messages in the console
while restoring.
