Because netBackup will assign out of the scratch pool into any pool that
needs it, you can use the scratch_pool as the "low water mark". The
previous administrator here had modified the available_media script in
goodies under 3.2GA to provide a summary of all pools. I've just tried the
same thing on a test basis in our 3.4.1 environment and it still works. (He
was also bugged by how slow it ran so he added some code to cache the output
better. I haven't done anything with that yet :-)
Basically near the end of the available_media script, add a section like:
...
/bin/echo "" >>/tmp/avail_media_sorted_output
fi
done
# ------------ Section added to add summary info GBO Sept 20, 2002
/bin/echo "Summary:"
/bin/echo ""
/bin/echo "#Media Pool Type State"
/bin/echo "------ ---------- ---------- -----"
/usr/bin/nawk '{
if ( $2 == "pool" ) pool = substr($1" ",1,10)
if ( NF == 9 ) s[pool" "substr($2" ",1,10)" "$9]++
}
END {
for (state in s)
printf("%6d %s\n",s[state],state)
}' /tmp/avail_media_sorted_output | sort +1
# ------------ End of Section added to add summary info GBO Sept 20, 2002
/bin/echo
"media${TAB}media${TAB}robot${TAB}robot${TAB}robot${TAB}side/${TAB}ret
size${TAB}status"
...
I copied a few of the existing lines so you know where it can be inserted.
We have a Solaris environment, your mileage may vary, your next upgrade will
overwrite this script etc.
If you graph the number of tapes in the scratch_pool you'll get a steadily
decreasing line. (At best flat, since NetBackup never puts any tapes back in
:-)
But one thing is different here: Our shop doesn't keep ANY images forever
:-)
I hope this helps....Gerrit
