IT35250: AFTER UPGRADING IBM SPECTRUM SCALE TO 5.0.5 OR HIGHER ON LINUX, DSMMIGRATE GETS ANS9298W ON FILES WITH ACLS

APAR status

• Closed as program error.

Error description

• After IBM Spectrum Scale is upgraded to version 5.0.5 or higher
  on Linux, dsmmigrate records error ANS9298W if the file have
  ACLs even though its latest version of backup copy has already
  been taken.
  
  ANS9298W File 'path_to_file' is skipped for migration: Backup
  copy found is not current.
  
  The issue can occur with IBM Spectrum Protect for Space
  Management versions earlier than 8.1.11, but note that IBM
  Spectrum Scale 5.0.5 is supported from 8.1.9.
  
  Customer/Support Diagnostics:
  In the client SERVICE trace, it can be seen that only the change
  of 'Xattr' was detected unnecessarily.

• After the fix, incremental backup and migration operations will
  work as expected regardless of the current (supported) IBM
  Spectrum Scale version in use.
