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.
    For example:
