The DLT does send these signals, but NetBackup does not get them.  Only the 
library gets them, and reacts appropriately if you have set it up to auto 
clean itself.  Netbackup (and every other backup software package that I 
know of) only cleans every X hours of operation, which is the WRONG way to 
clean a DLT drive.
