NOTE: For the Encryption Key Identier 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 le on the system where Distributed Web Server is running, select the

Escrow check box.

The Path eld is displayed. Provide the path where you want to save the le. The path should contain a lename with an .xml

extension. The saved le contains the information: SAS address, Encryption Key Identier, Passphrase, and modied date. You

can use this le 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.

NOTE: If Encryption Key Identier or Passphrase contain special characters such as & , " , <, and >, in the le, they

are written as & , ", < and > respectively.

NOTE: If the system crashes while saving the le, the backup le is saved in the specied location.

5. Select the check-box indicating that you understand the implications of using a passphrase and click Apply Changes.

In the controller Information/Conguration page, the Encryption Key Present is set to Yes and the Encryption mode is set to

LKM.

Changing Or Deleting The Encryption Key

You can change an encryption key of a controller if the controller already has a congured encryption key. You can delete an

encryption key for encrypted controllers only if there are no encrypted virtual disks.

To change the encryption key, type the New Encryption Key Identier and Passphrase. You are prompted to authenticate the

current Passphrase. Ensure that you read the note on the importance of passphrase and consequences of not saving the same,

before applying the changes.

When you change the encryption key, the existing conguration on the controller is updated to use the new encryption key. If you

have removed any of the encrypted drives previously, you must authenticate with the old passphrase to import the encrypted drives.

When changing the encryption key, you can also save or update the new encryption key credentials to a le in the system where

Distributed Web Service is running. Select the Escrow check box. If you have already saved the encryption key credentials for a

controller, providing the path of the le updates the credentials for that controller. If the credentials are for a new controller, the

details are appended in the same le.

If you have not saved the credentials to a le, you can provide the path on which the le must be saved. The path must contain a

lename with an .xml extension. On applying changes, this le is created with the credentials.

If you delete the encryption key, you cannot create encrypted virtual disks and all encrypted uncongured self-encrypting drives are

erased. However, deleting an encryption key does not aect encryption or data in foreign disks. If you have saved the encryption key

credentials to a le, deleting the encryption key does not delete the le. Managing the le is the responsibility of the administrator.

Managing The Encryption Key

NOTE: This task is not supported on PERC hardware controllers running in HBA mode.

NOTE: To congure encryption, SED is not required. The encryption settings are used to congure the virtual disk and

the SED.

NOTE: On controller when encryption is disabled, manually enable encryption for virtual disks created using SED drives.

Even if the virtual disk is created after a controller has had encryption enabled, to create an encrypted virtual disk the

encryption option must still be selected from the Advanced Wizard during virtual disk creation.
