I don't think you can put the drive offline while it has a drive mounted
and in-use.

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.
