Kevin,
I have not done this before, however I waspondering how I might actually
perform it.
Just some thoughs, Not knowing exactly what netbackup is trying to do at
the time,
How long does it take to erase the tapes in question ?
Did you background your "erase_media.pl" script called by
deassign_notify ?
Also, I might suggest put a sleep in the perl script for <undefined
period here> to allow netbackup to finish performing it's thing before
you go erasing the tape.
My thoughts.
Adam.

Subject: [Veritas-bu] labelling a media when it is deassigned
I am currently running Solaris 9 with NetBackup 6.5, and a EMC CDL720
(virtual tape library). I have over subscrided to help reduce the
amount of multiplexing that I do, so I have to quick erase the tapes as
they are deassigned.
When I upgraded to 6.5, I saw the
/usr/openv/netbackup/bin/media_deassign_notify script, and figured I
could just throw my bplabel command within this. Well, the first issue
I ran into was that NB is not passing the correct # of parameters to the
script. Well, after I got around that, I needed more than the media id
to run bplabel, so I wrote a perl script.
Well, when I run the perl script by hand, it works great! When I run it
under the media_deassign_notify it reflects the correct options on the
bplabel command but it freezes vmd. What do I mean? I mean it I can
not select any tapes and I can not kill the erase job on the activity
screen. I have to do a UNIX kill to get rid of it.
Below is what I wrote, but my question is does anybody else already do
this? If so, I would appreciate any direction on what I have done
wrong.
This is the line I added in the media_deassign_notify:
/usr/openv/scripts/erase_media.pl $1
Here is the perl script:
#!/usr/bin/perl
#
# This script was created, because the CDL does not release space
already allocated. So
# when a virtual tape is used on the CDL and uses 200GB, it does not
release that space after
# the tape is unassigned. This is being called by
media_deassign_notify
#
#
open (LOG,">/tmp/erase_media.log") || die("can not open file");
$#rv=-1;
@rv = (split ' ', `/usr/openv/volmgr/bin/vmquery -l -m $ARGV[0]
|/usr/xpg4/bin/awk '{print \$1,\$8,\$12,\$15,\$20,\$21}'`);
# ###############################################
# check to see if it NOT robot 3 (physical robot), and the assign date
is empty, and the # of mounts is greater than 0
# ###############################################
if ($rv[1] != "3" && $rv[1] gt -1 && $rv[4] == "00/00/0000" && $rv[3] gt
0) {
print LOG "Erasing.... " . $rv[0] . " Pool " . $rv[2] . "\n";
system `/usr/openv/netbackup/bin/admincmd/bplabel -erase -m $rv[0] -d
hcart2 -o -p $rv[2]`;
} else {
print LOG "Not Erasing.... " . $rv[0] . " Pool " . $rv[2] . " Robot "
. $rv[1] . " Date " . $rv[4] . " Mounts " . $rv[3] . "\n";
}
close(LOG);
