Enable Encryption
- If you lose the passphrase for the master encryption key or access to the external key manager, data in the encrypted volumes cannot be retrieved.
- The encryption status of a volume cannot be changed.
Based on your selections for Default Setting and Scope, volumes that authorized users create after enabling encryption are either automatically encrypted or can be encrypted on a case-by-case basis.
NOTE: Volumes that were created in versions
earlier than version 2.3.x are not encrypted and cannot be edited to be encrypted.
The encryption state specified when creating a volume cannot be changed for the life
of that volume.
