Why don't you just create the NEW drives as HCART2, then all new Media
(9940B) as HCART2 media that will ensure your success in keeping the
HCART media from being mounted in an HCART2 drive.

In my consulting days, I had a client doing the exact same thing you are
attempting and creating a second (or third depending on your
environment) MEDIA and DRIVE type (HCART2) solved everything.

Now remember, you'll have to create new Storage Units too that are of
type HCART2 and then modify your backup policies.

However, if you aren't keeping a 9940A drive around, then you'll have to
"freeze" the media.


bpmedialist -h $HOSTNAME -l | while read id rest
do
bpmedia -m $id -freeze
done

If you suspend the media then it will not be available for writes until
the last image on the media expires.  At that point it will be available
for writes again.  When you freeze media, it is not valid for writes
until you UNFREEZE it again later.

Hope this helps.

Subject: [Veritas-bu] Re: Listing tapes in a media server's media
catalog

Ok, I hate responding to my own emails, but I think I have an idea:

Using vmquery, identify all tapes with an assigned date.
For each of those tapes, do this:

to get the media server that owns the tape, do:
bpimmedia -mediaid $VOLSER | grep IMAGE | awk '{print $2} | uniq

to suspend the tape, do:
bpmedia -suspend -ev $VOLSER -h $HOST

I left out some details (like how $VOLSER and $HOST get assigned), but 
does this sound like it will do what I want?
