IT17191: CROSSED-PROTECT SERVERS CAUSED ORPHANED CHUNKS IN CONTAINER STORAGE POOLS.

APAR status

• Closed as unreproducible.

Error description

• Crossed-protect servers are defined as the two servers
  protecting one another using PROTECT STGPOOL command. Using this
   configuration, the container storage pools on both servers may
  have orphaned chunks, causing the storage pool space utilization
   to increase gradually.
  
  This problem has been fixed in IBM Spectrum Protect 7.1.7 or
  later. There will be no additional orphaned chunks created after
  applying 7.1.7 or later, but the existing orphaned chunks will
  need to be removed. See the local fix section for additional
  details.
  
  Tivoli Storage Manager Versions Affected:
  IBM Spectrum Protect 7.1.3 and later
  
  Customer/L2 Diagnostics (If Applicable)
  The following DB2 SQL can be used to determine if there are
  orphaned chunks (can be run from both servers):
  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.
  Note: The SQL provided is a generic query to detect orphaned
  chunks on the server and not necessarily applied to this APAR
  only. There are other issues that can cause orphaned chunks on
  the target server. You must be using the crossed-protect
  environment for this APAR to apply.
  Initial Impact:
