Error description

• In a replication environment, there are scenarios where orphaned
  chunks are created in container type storage pools on the
  target server. One such scenario is described by APAR IT14233.
  This APAR addresses the need for a new engine to automatically
  clean up orphaned chunks in container pools.
  
  Tivoli Storage Manager Versions Affected:
  IBM Spectrum Protect server 7.1.3 and later
  
  Customer/L2 Diagnostics
  The target container pool will use more space than the source
  container pool.
  The following DB2 command can be used to see if there are
  orphaned chunks (on the target server):
  db2 select poolname,poolid from ss_pools
  db2 "select sum(cast(length as bigint)) as sum, count as count
  from sd_chunk_locations cl where cl.poolid=<poolid> and
  (cl.chunkid, cl.poolid) in (select sdcl.chunkid, sdcl.poolid
  from sd_chunk_locations sdcl where refcount=1 and sdcl.chunkid
  not in (select sdro.chunkid from sd_recon_order sdro) and
  sdcl.chunkid not in (select sdrc.chunkid from
  sd_replicated_chunks sdrc) and sdcl.chunkid not in (select
  sdru.chunkid from sd_refcount_updates sdru) ) for read only with
  ur"
  
  Replace <poolid> with the container storage pool id.
  If the count returned is greater than 0, there are orphaned
  chunks in the storage pool.
