  • Closed as program error.

Error description

  • AFM Probelm. Hard links can be created at cache.
    Hard links at home are displayed as individual files in
    cache.
    There is a procedure for this
    but it is not working for all hard links.
    The fix will have hard link created correctly using
    
    mmafmctl prefetch with --list-file and --metadata-only?
    or also using ?mmafmctl prefetch with only --directory?
    
    Found in Spectrum Scale 5.1.1.4.
