Re: [Veritas-bu] erase option to bplabel does what?

Don't know if you're looking for a *nix script Darren (or if this thread
is long dead for you), but here's our script if you want it (I have a
Diligent Protectier v2 VTL, requires regular bplabel to clear newly
"Scratch"ed tapes so that the defrag process can kick in):

Cheers,
Jon
----------------------------------------------------------

[root@<snip> ~]# crontab -l
30 9 * * * /NB-scripts/cluster_label_script.sh

#!/bin/sh

# This script generates a list of media located on VTL which have
expired and     #
# have been returned to the Scratch pool since the last time the script
was run.  #
# It should be called on a regular basis from cron, or by a Netbackup
session     #
# notify script.
#

# generate a full current listing of all scratch tapes you want to
parse,  ours happen to start with the prefix "PD"
/usr/openv/volmgr/bin/vmquery -pn Scratch -b | grep PD | sort | awk
'{print $1}' > /tmp/temp1.tmp

# diff compares the curent list of Scratch to the list from the previous
#
# iteration of this script and stores the new IDs in a new temp file
#
/usr/bin/diff /NB-scripts/clus_prev.scratch /tmp/temp1.tmp | grep ">" |
awk '{print $2}'  > /tmp/temp2.tmp

# The script is finished with the previous iteration's info, so we clean
up       #
/bin/rm -f /NB-scripts/clus_prev.scratch

# we now bplabel all of the new Scratch media
#
for i in `cat /tmp/temp2.tmp`; do
/usr/openv/netbackup/bin/admincmd/bplabel -m $i -d dlt -o -p Scratch;
done 2>&1

# Once the bplabel is complete, we take today's list of total Scratch
and store   #
# it as prev.scratch for the next iteration.
#
/bin/mv /tmp/temp1.tmp /NB-scripts/clus_prev.scratch

# We also clean up
#
/bin/rm -f /tmp/temp2.tmp

Ah, interesting.  Are you just parsing one of the log files to create
that list, or do you keep state yourself?

For now, my count is low enough that I can just relabel all scratch in a
reasonable period of time.  But I was thinking of checking the VTL
directly for information about size used.  Of course doing that would
mean reducing compatibility and doing non-netbackup things.
