Managing LUN Encryption

Encryption can only be enabled during LUN creation. For details, see Creating a Block-Based LUN.

To manage other LUN settings, see the following topics:

  1. Go to one of the following:
    • iSCSI & Fibre Channel > iSCSI Storage
    • iSCSI & Fibre Channel > Fibre Channel > FC Storage
  2. Select an encrypted LUN.
  3. Click Encryption.

    A drop-down menu appears.

  4. Select an action.



    Change Encryption Password

    Change the encryption password.

    • If the encrypted LUN contains snapshots, you must remove the snapshots before you can change the password.

    • The password cannot contain the following characters or sequences: space ( ), dollar sign ($), colon (:), equal sign (=), HTML double quote ("), HTML backslash (\)


    Changing the encryption password also changes the encryption key. If you previously downloaded an encryption key file, you must download a new encryption key file.

    Download Encryption Key

    Download the encryption key file. You can use the encryption key file to unlock the encrypted LUN if you forget the encryption password.

    Enable Auto Unlock

    Allow the system to automatically unlock the encrypted LUN when the NAS starts.

    Disable Auto Unlock

    Stop the system from automatically unlocking the encrypted LUN when the NAS starts.

    Lock LUN

    Lock the encrypted LUN.

    • Locking an encrypted LUN disconnects all existing connections to the LUN.
    • When an encrypted LUN is locked, you cannot perform the following actions:

      • Read and write data to the LUN

      • Map the LUN to an iSCSI target

      • Take snapshots of the LUN

    Unlock LUN

    Unlock the encrypted LUN with the encryption password or encryption key file.
