Applies to

  • ONTAP 9
  • NetApp Storage Encryption
  • External Key-Management

Answer

  • NSE drives have a built-in self-sanitization feature
  • If more than 1024 authentication attempts to the external key manager have failed, the drive will drop its internal Data Encryption Key (DEK).
  • When this occurs, all data on the drives will be lost and cannot be reverted.

Additional Information

As long as a node remains at the loader prompt and is not in a boot loop, authentication attempts will not be made therefore the count will not be increased.
