Transparently by accessing the stub file on the client.

It's some time since I've worked with TSM, so forgive if I am wrong,
but AFAIK accessing a file from a TSM client works the same, even after
the file has been moved to another, slower storage pool.

So, after 30 days, your file is in storage pool 'slow', and there is
a stub file on the client. If there is a nextstgpool 'slower' for this
storage pool, then after some time the file ends up in 'slower'.
The stub file on the client remains. When you access it, the file is
fetched from 'slower'.
