 Encryption Key File: Upload the encryption file to the CMS Server to unlock the disk
volume. The key can be downloaded from “Encryption Key Management” page after
the disk volume has been unlocked successfully.
Please note that the data encryption functions may not be available in accordance to the
legislative restrictions of some countries.
Click “ENCRYPTION KEY MANAGEMENT” on the “Action” column of an unlocked disk
volume.
You can perform the following actions:
 Change the encryption key: Input your old encryption password and input the new
password. (Note that after the password is changed, any previously exported keys will
not be working anymore. You have to download the new encryption key if necessary,
see below).
 Save the encryption key: Save the encryption key on the CMS Server for automatic
unlocking and mounting the encrypted disk volume when the CMS Server restarts.
 Download the encryption key file: Input the encryption password to download the
encryption key file. Downloading the encryption key file will allow you to save the
encryption key in a file. The file is also encrypted and can be used to unlock a volume,
without knowing the real password (see “unlock a disk volume manually” below).
Please save the encryption key file in a secure place!
