Andrew,

That's strange because Netbackup Support doesn't seem aware of severity of
cleaning request and possible ignores. 

I would have our operators do manual cleaning if I could but I've got 100+
drives which would become  cumbersome at best. I guess if I can't get this
to work I'll switch to frequency based cleaning.

Thanks for your help,

You are not alone....

DLT7000 Tape System Product Manual p.5-56 contains a list of 
TapeAlert Flags, Severity Levels, and Meanings for LOG SENSE
command. There are 9 flags, and 6 of them correspond to 
cleaning requests. 3 of them have Severity Level Critical 
and 3 just Warnings. I think NetBackup ignores Warnings 
and taking care of Critical errors, becous I've seen NetBackup
cleaning a tape drive.

You can ignore them too .... 
I am checking my library every day and clean a tape drive 
if I see a cleaning request on a front panel.

Thanks,
Andrew
