I just wrote up these crib notes... and I wonder if
there's anything wrong with them... or if some of you
some versed networker folks have comments about them?

all clients/tapes have one year retention policy

some/lots of tapes have not become recyclable because of
systems that no longer exist. we don't care about them.

ergo any tapes that expire before 4/1/2005 can be set
to recyclable... for example, the last three months...

for i in 01 02 03; do
mminfo -m | egrep "$i/.*/05"
vols=`mminfo -m | egrep "$i/.*/05" | awk '{print $1}'`
for v in $vols; do
echo nsrmm -y -o recyclable $v
nsrmm -y -o recyclable $v
done
done

Here's a different way to do it that might work better. I usually run a
script on my volumes that runs this:

mminfo -s $SERVER -q \!ssrecycle,\!recoverable,volume=$1

So, on a per-volume basis, mminfo will return any savesets on the tape
that aren't recyclable. I run this against tapes that I think should
expire, but aren't, and see which clients are 'hanging' the tape. From
there, I can query the clients or look through the indexes to see what
happened. You might run a similar report on your volumes.

A better idea would probably be to mark all the savesets from the
systems that no longer exist as recyclable. If that's true, than the
media should recycle/take care of itself without you having to do
per-tape operations.

Good idea.

That's got me wondering... I know of three states that cause tapes
to not become recyclable: "aborted saveset", "saveset in progress"
and "saveset for removed client"... are there others?
