IJ51711: POSSIBLE DUPLICATE SYMBOLIC LINK CREATED IN AFM NSD BACKEND TARGET

APAR status

• Closed as program error.

Error description

• If a mount is symbolic link is attempted on an existing symlink
  of a directory, then it ends up creating the symbolic link with
  same name as the source inside the target directory. Since the
  DR is mostly RO in nature, it ends up getting an E_ROFS and
  prints these failures to the log.
