I don't see a problem with it per se, but you can't actually push all 9
at full speed over one 2Gb/s link.  I've had 10 LTO1 drives in a zone
without any similar issues.

Could be.  If those drives are in only one zone, then that certainly
eliminates many different possibilities (like another host sending a
spurious reset).  Tracking down fiber errors is never fun.  Sysadmin
tools aren't very good at that level.

Make sure all the drives and switches are at recommended firmware
levels.
