Applies to

  • NetApp E-Series storage systems
  • Full Disk Encryption (FDE) or Full Disk Encryption with Data Assurance (FIPS/FDE drives)
  • Systems with secured drives using an external or internal key management
  • Dual-controller configurations

Answer

Yes, the Encrypted disks in NetApp E-Series remain accessible after a dual-controller replacement only if the original security key is restored.

Additional Information

  • In a simplex controller system or a dual controller replacement in a dual-controller system, you must provide the backed-up security key from the original controller. If a backup of the security key is not available, the data on the drives are not accessible.
