IT26288: RETRIEVING MPIO CONFIGURATION BY USING MPCLAIM COMMAND WITH -V OPTION CAUSES "ACCESS DENIED" ERROR

APAR status

• Closed as Vendor Solution.

Error description

• See this Microsoft support notification:
  https://support.microsoft.com/en-gb/help/3161579
  
  When the Encrypting File System (EFS) feature is disabled in
  Windows 2012 R2, such as by Group Policy, retrieving the MPIO
  configuration by using the mpclaim command together with the -v
  option causes an "Access Denied" error and doesn?t show the
  configuration.
  Note MPIO represents Microsoft Multipath I/O.
  
  The problem could be fixed by installing June 2016 update rollup
  for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2.
  However, after installing this update, mpclaim -v config.txt
  will continue to try to write to an encrypted file and won't
  work correctly when EFS is disabled.
  
  Therefore, besides to install the update mentioned above,
  Spectrum Control should change the SRA code to use -n flag for
  all mpclaim commands to avoid this problem totally.

  expected.
