Some possible improvements to reclamation:

1) Allow multiple reclamation processes.

2) For sequential volumes in collocated pools:

   a) Process all reclaimable volumes for one client before reclaiming
      the next client's volumes.
   b) Order processing such that the client with the largest number of
      reclaimable volumes is processed first, then the client with the
      next largest number of volumes, etc.
   c) If multiple reclamation processes are implemented, process one
      client's volumes per thread.
   d) Continue to use the same output tape for each reclaimable volume
      until the output tape is full, or reclamation for that client ends.
      For example, suppose the reclamation threshold is 90%. The client
      has 4 volumes as follows:

         vol1: 1% utilized
         vol2: 5% utilized
         vol3: 3% utilized
         vol4: 50% utilized

      Reclamation would occur as follows:

         - mount vol1 as input; mount vol4 as output; reclaim vol1 to vol4.
         - dismount vol1 and mount vol2 as input; reclaim vol2 to vol4.
         - dismount vol2 and mount vol3 as input; reclaim vol3 to vol4.
         - dismount vol3 and vol4.

3) For non-collocated pools, process reclaimable volumes in order of least
   utilized to most utilized (up to the threshold). Continue to use the same
   output tape for each volume until the tape is full.

Thank you for your consideration.
