AFD protects from unauthorized processes over write to the asm claimed disks
in raw disk environment which is not applicable to exadata disks (non-oracle processes could not recognize / write to exadata disks).

so the message “FD-0654: AFD is not supported on Exadata systems” in alert.log can be ignored.
