Encryption Key
The controller uses the encryption key to lock or unlock access to SED. You can create only one
encryption key for each encryption-capable controller.
If you are using LKM, you must create the encryption key by providing the Encryption Key Identifier and
the Passphrase.
Encryption Key Identifier
An Encryption Key Identifier is a user-supplied text label for the Passphrase. The identifier helps you
determine which Passphrase to provide while authenticating import of foreign encrypted SED drives.
Passphrase
A Passphrase is a user supplied string that the controller uses to create the encryption key.

Creating An Encryption Key And Enabling LKM
To create an encryption key on the selected controller:
1. Select the Enable Local Key Management (LKM) option.
2. Type Encryption Key Identifier.
An Encryption Key Identifier can contain numerals, alphabets both lower and upper case are
allowed, non-alphanumeric characters, or a combination of any of these.
NOTE: For the Encryption Key Identifier and Passphrase guidelines, click the icon on the
page.
3. Type a Passphrase.
A Passphrase must contain at least one numeral, alphabets both lower and upper case are allowed,
and one non-alphanumeric character (except space).
NOTE: Server Administrator Storage Management provides a suggested passphrase below the
Passphrase text box.
4. If you want to save the Encryption Key credentials in a file on the system where Distributed Web
Server is running, select the Escrow check box.
The Path field is displayed. Provide the path where you want to save the file. The path should contain
a filename with an .xml extension. The saved file contains the information: SAS address, Encryption
Key Identifier, Passphrase, and modified date. You can use this file for future reference.
CAUTION: It is important to understand that if you lose the Passphrase, you cannot recover
it. If you move the physical disks associated with the lost Passphrase to another controller or
if the controller fails or is replaced, you cannot access data from that disk.
