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.

NOTE: If Encryption Key Identifier or Passphrase contain special characters such as & , " , <, and >, in the file, they

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

NOTE: If the system crashes while saving the file, the backup file is saved in the specified location.

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

In the controller Information/Configuration 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 configured 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 Identifier 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 configuration 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 file 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 file updates the credentials for that controller. If the credentials are for a new controller, the details

are appended in the same file.

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

with an .xml extension. On applying changes, this file is created with the credentials.

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

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

credentials to a file, deleting the encryption key does not delete the file. Managing the file 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 configure encryption, SED is not required. The encryption settings are used to configure 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.

On an encryption-capable controller, the Manage Encryption Key task allows you to enable encryption in LKM mode. If you enable LKM,

you can create an encryption key on an encryption-capable controller and save it locally. You can also change or delete the encryption key.

NOTE: This task is available only on PERC H7x0 and H8x0 controllers.
