Ray,

I had the exact thing happen to me last week at a site with a 3570.  After
removing the tape from the drive, TSM still reported that the tape was in
the drive regardless of all my efforts.  I had the top off the robot and I
could see that TSM tried to perform an unload on the drive every time I
brought it back up, even though the tape was out of the library.

Finally, I inserted the tape that TSM said was in the drive using the
service menu on the front panel and loading the tape through slot 31.  I
could then unload it via TSM and everything was back to normal.
