Answer

  • The ONTAP option encryption.create.unique.clone.key.disable is used to control the behavior of key management for cloned volumes in an ONTAP environment.
  • When this option is disabled (set to "off"), which is the default state, ONTAP generates a unique encryption key for each clone created.
  • This ensures that each clone has its own separate encryption domain, providing a high level of security.
  • However, when this option is enabled (set to "on"), ONTAP will not generate a unique encryption key for each new clone.
  • Instead, clones will share the same encryption key as their parent volume.
  • This behavior can simplify key management and may improve cloning performance, but it also means that if the encryption key of the parent volume is compromised, all associated clones that share the key would also be compromised.
