Sorry for the late summary. I decided to take the weekend off!

Ok, my main question was sometimes when I do a "boot -r" Solaris just
decides to increment the device number of my tape drive. I just wanted to
know how to reset this. Two ways, one with a reboot, one without. I haven't
tried the without method however.

# cd /dev/rmt
# rm *
At this point you could reboot(boot -r) or run the following.
# drvconfig
# tapes
# devlinks
# /usr/ucb/ucblinks

hmm 2.6 :( have you check if there is ANY st. patch available that you
might not have installed yet???
