We have an IBM 3583 LTO Library defined to TSM with cleaning frequency as
"ASNEEDED".

We have been running it in production for 2 months and have not noticed any
cleanings yet.

We have the cleaning messages automated so that when a drive is cleaned we
get notified.  Also by looking at the "Cleanings Left" on the cleaning
cartridge via a q libv we know that no cleanings have been done.

Just curious how often people have seen these drives needing cleaning.

Thanks for any info!
