MOVE NODEDATA will move data for a particular client from one copy pool
tape to another as long as the operation is contained within the same
copy pool.
However, give this thought some thought: running MOVE NODEDATA prior to
disaster recovery drill isn't a true test of disaster recovery, since
you would not have a chance to run MOVE NODEDATA prior to a real
disaster.
If restoring a client's data from a copy pool is taking too long for a
disaster recovery drill, it will take too long in a real disaster.
Reconsider collocating your copy pool tapes, or at least consider
creating a collocated copy pool for just those clients who must be
restored quickly.
