The trouble with frequency-based cleaning in an SSO environment (if you're
SSO) is that the usage data isn't aggregated anywhere (at least in v5.x &
down).  If you're not SSO, then I'd recommend a simple frequency per drive.
 
For SSO, the official response is to use Tape-Alert cleaning, the drive can,
supposedly, call for a cleaning when needed.  I haven't had much success on
this, though.
 
If you use library-based cleaning, then sometimes you'll get into trouble.
The library will decide to clean a drive and not inform Netbackup.  Then
Netbackup will attempt to mount a tape in the drive with the cleaning tape,
fail, and then DOWN the drive on you.  Annoying. 
 
One day, I need to wrrite something that aggregates SSO usage data and
initiates a tpclean on my own defined frequency.

Good Morning.
Well so far, I am having alot more successful backups. I get the very odd
status 84 message appear, but the backups do continue and complete.
 
Looking into this more, I wonder if my drives need cleaning. I have
purchased 2 tape cleaning media's - is there a way I can configure in
Netbackup to "automatically" clean the drives??
 
Or do you have to use TPCLEAN? For example, I will stick the cleaning tape
in slot 1 - can a schedule be set to clean tapes or am I talking rubbish!?
 
Also, if anyone has any docs on how to put in a SAN Media Server, I would
TRULY apprecaite it!
 
Tried to implement a MEdia Server over the weekend, and clearly I am doing
something wrong because when I finally got it up and running, all I was
seeing was a mirror image of what my master is seeing! And although I am
trying to configure the SAN Media Server to go through a fibre backup,
rather than LAN, this does not seem to be happening!
 
Thanks to everyone with all of their help and input!
 
Simon
