If, thru the Networker gui you go:  MEDIA   JUKEBOX   change AUTOCLEAN to
yes    Networker will check on each tape load to see if the drives require
cleaning, If they do it will load the cleaning tape prior to whatever tape
is was going to load.  This is not a schedule.  The cleaning tape only loads
when the drive requests cleaning.

library?


Based on our experience, we use the Library cleaning option. The tape
library will be able to sense the tape drive's request for cleaning. If
you set or schedule the cleaning thru Networker, you might end up
damaging the heads because of frequent cleaning even though the drives
aren't dirty yet or the worst scenario is that you might have damaged
media due to dirty heads. The tape drives needs to be cleaned, but they
are not scheduled to be cleaned yet by Networker, so they stay dirty
until the cleaning schedule is reached.

Hi,

We're running a Storagetek L80 with 4 LTO gen 1. drives (Seagate).
Using
NetWorker 6.1.1 on primary (Solaris) and storagenode (Linux). We can
set
up cleaning from the library or NetWorker. Can someone suggest which
method is best? Obviously, we don't want both, but not sure which way
to
go.

Storagetek tells me that they have customers doing either of the two
methods. I'm concerned that if we set up the cleaning from the library
that the library will take the drive off line when it needs to clean
it
and NetWorker could either be using the device or preparing to and
that
might cause problems, so I'm leaning toward setting this up from
NetWorker for proper hand shaking, but I'm open for suggestions.
Another
concern, though, is this: if I set up automatic cleaning from
NetWorker,
will the library in fact tell NetWorker that the drive(s) needs to be
cleaned? The library is supposed to relay this info/request to the
software, correct? Does this work properly on the Storagetek
libraries,
anyone?

Thanks.

George
