There's really no configuration to do. Once Netbackup knows that it has a
cleaning tape in the library, it will automatically react to a Tapealert.
The feature is permanently turned "on". If you also want to do scheduled
cleaning, you can set it up using tpclean as you've already done; the two
cleaning methods won't interfere with each other.
As you pointed out, of course, not every library, drive, firmware revision,
etc. fully supports Tapealert; most do, though. I don't know about your
specific case.

Subject: Re: Tape Alert Setup
Hello Larry
Hmmm, I remember going through the manual for 3.4 very carefully before I
set
up the cleaning tapes at this site.
There is a blurb on page 286 about TapeAlert that states that not all
robots,
drives and firmware levels support reactive cleanings but that if yours did
you
could do both frequency based and reactive cleanings. Never found out how.
The blurb references a chart on page 276 that basically said "yes" for TL8,
a
lot of good that does.
It's a feature that I wanted to turn on, tried very hard to find info on it
in
the manuals, but didn't find anything useful. Maybe you can tell me how to
use
TapeAlert, I've got an ADIC Scalar 1000 with Sony AIT2 drives.

John's comment below isn't quite right... as Alexander implied, Netbackup
(V3.2 and higher) is also capable of sensing a Tape Alert request from a
drive. It's not just time based.
John is correct when he says that Netbackup won't recognize a cleaning tape
by default... you must first create a barcode rule that looks for the
cleaning tape's barcode prefix (typically CLN); you must configure the rule
to define tapes with this prefix as DLT cleaning tapes, and you should set
an appropriate maximum number of cleanings (always 20 for DLT cleaning
cartridges, as far as I know). There is no additional configuration needed.
If the drive supports Tape Alert, and Netbackup knows that it has a cleaning
tape available, it will automatically initiate a cleaning cycle when the
drive signals that it needs one. You don't need to use tpclean to make this
happen.

Hello Alexander
Netbackup's cleaning algorithm is strictly time based i.e.: it keeps track
of
how many hours a given drive is in use and once it reaches a certain value,
the
cleaning tape is run through it. Many robots have the ability to sense
when a
drive requests cleaning and therefore minimize your cleaning cycles to the
absolute minimum number of cycles needed, these have little wires plugged
into
the jumpers on the back of the tape drive.

NB Users:
Can anyone explain the steps I need to do to enable Tape Alert on our NB 3.4
setup, we currently have the STK 9710
robot doing the cleaning and we change the tape after 20 cleanings. All I
know I
must shutoff the robot cleaning, add a
cleaning tape with a CLN bar code to robot & inventory it.
What else and is there and is there a correct sequence ?
