Hi Tim,
I'm by no means an expert of this matter, I have asked questions of
engineers and from what I've read/observed, this is how I understand the
Hardware Cleaning takes place.
First off, you must have a cleaning cartridge in the Tape Library and it
must "see it". I have a STY 9714 library, my cleaning tape MUST go into slot
00, this is a reserved slot. I also had an issue a few months ago were I
couldn't use the front menu to exchange the cleaning tape, apparently this
was fixed with a STY firmware upgrade as it started working after I had the
engineer upgrade my libraries firmware.
Within Veritas turn-off it's capability for cleaning the drives. Veritas now
won't monitor when the drives need cleaning. What you want to happen is for
the library to "sense" when a drive requires cleaning and let the library to
it rather than cleaning after X number of hours use.
The down side with the hardware cleaning is that you have to monitor when
the cleaning tape has expired (after 20 uses). My library allows me to view
how many times the cleaning tape has been used and also when the cleaning
tape has expired it displays and asterisk (*) on the main menu of the
library.
I'm running NUB of a HP platform, HP have a product called EMS which can be
used to inform me when the Cleaning Tape has expired, at the moment I'm
looking at this to build a script around it.
Hope this helps.

Subject: RE: [Veritas-bu] Autocleaning of drive in STK L700
I have a question on a similar topic to the above.
I have a DLT7000 tape library. How does the (hardware) automatic tape
cleaning work? I am currently using frequency cleaning at the moment but
I have been told that you should not do this...
I have the cleaning tapes in the None group. Does the tape library ask
netbackup for a cleaning tape and netbackup will process and clean the
drive?
Cheers,
Tim.
