Interestingly I'm seen at my site that a large partition, which might fit on a tape, can be not-the-first on a tape and hit EOT while being written, it will then dump to a second volume (if jukebox == 1).
You can have a similar cascading failure if you try to put another DLE on the end of the second tape volume, rolling onto the third. You can have a senario where the single DLE would have fit properly on the 1st tape volume had the large interviening DLE not put put to tape before it. taper ordering is a critical thing sometimes.
