The following is from the Windows NT Administrator guide

2.6.7.3 Reclaiming Volumes in a Storage Pool with One Drive

When a storage pool has only one mount point (that is, just one drive)
available to it through the device class,
data cannot be reclaimed from one volume to another within that same storage
pool.

To enable volume reclamation for a storage pool that has only one mount point,
you can define a reclamation
storage pool for ADSM to use when reclaiming volumes. When ADSM reclaims
volumes, ADSM moves the
data from volumes in the original storage pool to volumes in the reclamation
storage pool. ADSM always uses
the reclamation storage pool when one is defined, even when the mount limit is
greater than one.

If the reclamation storage pool does not have enough space to hold all of the
data being reclaimed, ADSM
moves as much of the data as possible into the reclamation storage pool. Any
data that could not be moved to
volumes in the reclamation storage pool still remains on volumes in the
original storage pool.

The pool identified as the reclamation storage pool must be a primary
sequential storage pool. The primary
purpose of the reclamation storage pool is for temporary storage of reclaimed
data. To ensure that data moved
to the reclamation storage pool eventually moves back into the original storage
pool, specify the original
storage pool as the next pool in the storage hierarchy for the reclamation
storage pool. For example, if you
have a tape library with one drive, you can define a storage pool to be used
for reclamation using a device
class with a device type of FILE:

  define stgpool reclaimpool fileclass maxscratch=100

Define the storage pool for the tape drive as follows:

  define stgpool tapepool1 tapeclass maxscratch=100
  reclaimstgpool=reclaimpool

And finally update the reclamation storage pool so that data migrates back to
the tape storage pool:

  update stgpool reclaimpool nextstgpool=tapepool1
