NSE: How to enable drive authentication on a NSE spare drive replacement

Last Updated:

Applies to

  • NetApp Storage Encryption (NSE)


This article describes the procedure to assign drive ownership of a replacement self encrypting disk (SED) and rekey the replacement drive.

  • NetApp Storage Encryption (NSE) drives are always encrypted regardless of the key ID in use.
  • When a hard drive is replaced on a NSE Storage System, the storage administrator must manually rekey the new spare drive with a valid key ID and authentication passphrase to protect the data on the drive.
  • By default, the replacement SED is set with the MSID (Mfg Secure ID) of 0x0 and the drive is not securely protected or locked.
  • An unlocked drive or a drive with a keyID of 0x0 does not require a keyID or passphrase authentication for data access.
  • It is extremely important to rekey the spare drive with the current keyID (ONTAP 8.3 and higher) and lock the drive (ONTAP 8.3 and lower) to protect the data prior to using the drive in production.
