We had this exact issue with Emulex cards, except that rebooting a Windows
box caused 84 errors on all running Windows backups. The Unix backups,
however, were never affected.
This Emulex issue was only fixed with the latest driver for the LP8000 and
LP9002 cards under Windows, and that was only released last September.
We use JNI cards for disk only under Solaris, with Emulex for tape. And all
Emulex for Windows.
And I have 2003 on short final, so it's going to be a busy Spring...<g>

I would really recommend against sharing fibre devices between Windows and
Unix.
1. Everytime you reboot you are going to cause PLOGI's on the fabris, and
you know Windows reboots a lot, since you are running JNI cards you will
have problems because their implmentation of FCP2 error correction isn't
quite complete. So rebooting a Windows machine could cause backups on the
Unix box to fail (this assumes you are running JNI in the Unix boxes if not
ignore this).
2. There are (or were as of last Sept) issues with SSO on Windows, it
doesn't play nice with Unix, Windows will try to reserve the drives even
when not in use. So be aware, the Unix box might not get to use the tape
drives when it needs to.
3. I noticed other people mention tape number changing on Windows, seen this
too, there are issues with JNI and persistant binding on Windows, and if
stuff moves around it will completely hose your SSO config.
If you really want to mix them, I would at least switch to Emulex, where
FCP2 works completely and there is a special Windows persistant binding
driver so stuff doesn't move around.
