I have observed that the tape drive dismounts the tape at the end of the
transaction it is processing and mounts the tape in another drive if
available.  Now, that may have been just a coincidence.

Subject: Varying tape drives offline


Anyone know what happens when you have processes/sessions running and using
tape drives and vary the drives offline with the command:
  update drive LIB DRIVE online=no

Do the tapes get dismounted?  Processes/sessions terminate?  Data corrupted?

3590 drives in a 3494 library running TSM 5.1.1.6 on AIX 5.1 if it makes any
difference.
