[Veritas-bu] Re: DLT Cleaning

Question about DLT Cleaning.

We turned auto clean off on out STK 9710.  We also added 5 DLT per each Silo for
DLT-CLN. Last night we received a lot of media errors, status code 84 -86. Non
of the drives were clean. I didn't open the robot  to see if cleaning lights are
on. Any suggestions. Is there anything else we need to do to get the cleaning to
work?

Thanks, Brian

Damn! Just when I thought I knew everything! ;)  If this functionality
works, this is a Beautiful Thing (tm).
Does anyone already have a script that uses cleanstats and complains if the
cleaning tape is out?

Something that Curtis didn't mention (I bet he wasn't aware of the
functionality, as it's certainly never made clear in the NetBackup GUI, but
it's mentioned on p.309 of the Media Manager 3.2 Admin Guide) is the fact
that NetBackup can control the cleaning tape *no matter which method you
choose* - time-based or demand-based.
