The answer to your question is a qualified no because I cannot think of a
way to safely do it.

The concept of a copy pool is to be able to protect the data in two
locations.  And DRM is the vehicle to support that.  What you really are
trying to do is a archive using primary copy pool tapes which is not what
TSM was designed to do.

As I see it you only have one choice here.  You will have to roll your own
tape movement thing.  With primary tapes you have to mark them to
unavailable using an UPDATE VOLUME vvvvvv ACCESS=UNAVAILABLE.  You can
probably create a SELECT statement that meets your criteria to create the
command as follows:

Select 'UPDATE VOLUME ', volume_name, 'ACCESS=UNAVAILABLE' from volumes
where stgpool_name='TAPEARCH' and volume_name in (select volume_name from
libvolumes) > /mark.cmd

This gives you all the tapes in your library that are in the storage pool.

Run this output as a macro command after striping off the first 2 lines.

Then do another select:

Select 'CHECKOUT LIBVOLUME ', library_name, volume_name, 'other appropriate
parameters' from libvolumes where  volume_name in (select volume_name from
volumes where access='UNAVAILABLE') > /eject.cmd

Run this the same way as above.

At this point the tapes should be checked out of your library and TSM should
not try to do anything with them.

Now, I have not tried this so you will have to do some significant testing.
There may be something I did not consider.

The real negative piece here is you have to manage what expires and is ready
to be put back in the library.
