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.

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.
