Thanks Richard, that is all set and working OK.  I have 3 storage pools(File) 
and 1 tape pool, and I setup pool 1 to go to pool 2, pool 2 to pool 3 and pool 
3 to tape pool, also setup the migration thresholds. Pool 1 has no more space 
and doesn't appear to be migrating, anyway I thought if I go to the ISC, policy 
domains, nodes, and move the data from pool 1 to tape pool would this work ok? 
I just don't want to break anything :) TSM has been running steady for 2 years!
 
Thanks again

Read the Admin Guide's description of "storage pool hierarchy".
The data can exist in any storage pool in the hierarchy, and be
accessed by the client.
