Depends upon your library type.
Seems normal for a 3494, where the drive signals both the attached
host and the library that it needs cleaning, and once the active data
tape is dismounted, the library-queued cleaning task can do its
thing, using a cleaning tape. Whereas the cleaning is by the library,
there is no host or TSM involvement, and no subsequent messages there.
