Error description

• The AUDIT CONTAINER with Action=SCANALL, may fail to mark
  extents as damaged in non-dedup (NCF) containers
  with zero-byte file size on Windows platform,  reporting only
  the following message in the activity log output :
  
  ANR4992W   Audit command has encountered an I/O error
  for container C:\abc\00\0000000000000005.ncf  in container
  storage pool STGPOOL1 while attempting to read a data extent

  Audit container is not properly handling the zero-byte container
  in this case.
  
  
  Instead, after the command execution, the non-dedup container
  will still be shown in AVAILABLE state
  by QUERY CONTAINER, and no damaged extents are reported.
  
  
  
  
  
  IBM Spectrum Protect versions affected:
  Server 7.1.3 and higher and 8.1 on Windows platforms only
  
  
  
  Initial Impact:
  Medium
  
  
  Additional Keywords:
  TSM "Spectrum Protect" container zero size ANR4992W "AUDIT
  CONTAINER" not marking damaged available windows
  

Local fix

• First run 'backup db type=snapshot'
  
  Then run for the affected container:
  'AUDIT CONTAINER <CONTAINER_NAME> ACTION=MARKD'
  
  which will mark all data extents in the zero-byte container as
  damaged.
  
  Then  run 'Q DAMAGED POOL_NAME TYPE=INVENTORY' to find the files
  that will be needed to re-ingest.
  During the re-ingest from backups, the damaged extents in those
  containers will  be re-linked to incoming extents.
  
  Or, 'repair stgpool' can be used to recover damaged extents, if
  the directory-container storage pool was protected by 'protect
  stgpool'.
