I agree with Richard, the tapes won't all go to scratch, they will go to
INSERT status.

If you have to go that way, I don't think it will be a big deal.

1) Checkout all your tapes from TSM with REMOVE=NO.
(You can use SQL to generate the commands to do them all at once, no need to
do it manually; let me know if you need help with that.)

2) When your service people are done and the tapes are in INSERT status, run
a checkin using VOLRANGE to check in tapes in the library into SCRATCH
status.  TSM is smart enough that you will get an error message for each one
that is defined in the DB or VOLHISTORY, saying you are NOT ALLOWED to check
them in as scratch.  So your scratch tapes will be checked in, the private
tapes won't.

3) Run another checkin using VOLRANGE to check in the tapes with

Voila.  Everything back to normal.

Hi Richard,
That way is the second possible way to migrate. My service people told me
that for this way they have to upgrade the library-manager on the existing
pc. Then they could backup the database, connect the new pc import the
database and all should be fine. They told me that they sometimes had
problems with this way and then there would be no way back.

And I don't know which one is the better way.

Christoph - An interesting situation there...

For the effects of a change implemented in that manner, refer to
"Re-inventory complete system" in redbook "IBM TotalStorage Enterprise Tape:
Practical Guide".  (All tapes end up in Insert category. To be avoided.)

Your IBM service people should be aware of better approaches...
The Library Manager consists of the industrial PC, LM software, and a
database.  The database is a logically separate entity, and can be handled
in pretty much the same way as any other database can, to the best of my
knowledge, which includes preserving its contents across a hardware change.
If you activate the Service Menu portion of the control panel menu
under Utilities you will see "Backup database..." and "Restore database...".
Your service people should be exhorted to fully pursue the potential there,
and not needlessly disrupt the customer environment.  Remind them that this
is Enterprise level hardware and software, which implies continuity without
untoward disruption.
