Actually, DLTs should also be cleaned on demand only. Check your manuals.
That's why I set up all my libraries to auto-clean, and I don't have
NetBackup do anything WRT cleaning. Unlike other drives, DLTs should not
be cleaned every X hours. Both DLTs and AITs are self-cleaning to a degree
(AIT much more than DLT), and cleaning them more often than they need
cleaning actually does harm to the drive.
