APAR status

• Closed as program error.

Error description

• Extended Attributes, ACLs, or Alternate
  Data Streams, not be restored for zero length files
  when TSM compression is used.
  
  The restore will not report any warnings or error messages.
  
  This applies to Windows, Linux, Solaris, AIX, and Mac OS X
  HPUX is not affected.
  
  For Mac, HFS+ compressed file data is stored as Extended
  Attributes. Beginning with Mac OS X 10.9, the files and
  applications provided by Apple are compressed files.  Restoring
  these files will remove their content and render them useless.

  ****************************************************************
  The problem was introduced by the fix for IC93914 which added
  a check for the file size before committing previously
  compressed data to disk.  If the size is zero, the expanded
  data is dicarded
  

Problem conclusion

• The fix for IC93914 was converted to use testflag
  DISCARDZEROFILEDATA to discard expanded data found
  during the restore.
  

Temporary fix

• Apply temporary fix level when available. This
  temporary fix is currently projected to be
  available in level 7.1.0.3.
  Note that until these level(s) are available,
  this information is subject to change at
  the discretion of IBM.
  Fixed in 6.3.2.3 (AIX, HP, Linux, Mac) and 6.3.2.4 (Windows)
