That's fantastic.  So I should probably do frequency based cleaning then
until I go to NBU 6.0?  The drives seem to need cleaning after about 500
or 600 hours of use.

Regards,
                   Brian

MP3

The best thing to do (for nbu versions < 6.0) is to ignore those  
lights. Those versions of netbackup only recognize two of the 48 or  
so possible flags set on the tapealert log page, clean now and clean  
periodic. The light on the front of the drive could get set for who  
knows how many of the other possibilities (ask ADIC or IBM). Also,  
the tapealert log page is a 'read and clear' log page, meaning if  
something (the library) reads it before netbackup then netbackup will  
never see that the flag was set, and take no action.

Netbackup 6.x will tell you which flag was set, and take action on  
many of them.
