We have been having several problems with 7.2. running on Solaris 10. 
Currently we have 3 drives  in service mode. We ran an nsrjb -HHE on them 
to clear them out and renabled them.  It then attempted to mount a new 
tape for labeling, an old tape for appending, and a recyclable tape for 
re-labeling.  All three of these operations resulted in I/O errors.  Much 
of what we saw earlier. We had a hardware tech come out a couple days ago 
and tell us it was a "leader" problem. He reset the leader on the drives 
and told us it was caused my bad tapes. Could this be more of the same 
"leader" problem we were having ??   We also have had problems where it 
would finish writing the tapes and  we would have to manually unmount the 
tape.  Also some tapes would get stuck on "verifying the label" this 
happens on random drives and random tapes. Just today a new tape got 
mounted for automatic labeling and failed, so we reset_device and it 
re-ran the process automatically and it worked.

Any suggestions, ideas, comments would be great. Also let me know if you 
need additional information.
