Page 13: Chapter 4. Managing Sed
Chapter 4. Managing SED Overview Introduction A Self-Encrypting Drive (SED) encrypts data through disk-based encryption with a Media Encryption Key (MEK). The MEK is known only to the SED and cannot be recovered through forensic analysis. Smart controllers enable the use of SEDs as logical drives or physical drives. The controller is responsible for managing and delivering the credentials required by the SED for enabling the disk-based encryption. - Page 14 Logical and physical drives Adapters support using SEDs for logical and physical drives with the disk-based encryption feature enabled. Encryption-enabled drives are referred to as secured drives. The controller delivers the credentials to the SEDs and unlocks them. SEDs can also be used for logical and physical drives without the disk-based encryption feature turned on (like a non-SED device) and is referred to as non-secured drives.

Importing a foreign secured SED A foreign SED is defined as a secured physical or logical drive that was previously attached to a controller with credentials different from those stored in the current controller. The controller can detect that the drive was moved from a different controller and can import the drive to the new controller when the original credentials are entered. - Page 16 1. Connect the supported SED to the controller. 2. Refer to system vendor documentation to establish connection between system and remote key management server. ™ 3. Enable SED management from HII, ARCCONF, or maxView . Choose the key management mode as remote. Master key generated by the key management server will be used for encryption.
- Page 17 the subsequent reboot if controller detects that the key management server is unavailable, then an unlock option will be provided in the UEFI HII menu. Controller can only unlock encrypted devices if the key management server is made available or by entering a valid controller password.
- Page 18 2. From the main menu, select Configure Controller Settings > Self-Encryption Drive (SED) Based Encryption Setup. 3. Select Unlock Controller. 4. Enter controller password, then select Submit. Note: In local key management mode, it is recommended to supply the password, before performing any operations such as removing or adding the drives.

Importing foreign SED Use the following steps to import foreign SEDs: 1. Boot to system BIOS setup utility and select controller to enter HII configuration utility. 2. From the main menu, select Configure Controller Settings > Self-Encryption Drive (SED) Based Encryption Setup. - Page 20 and new Master Keys. The management tools support retrieving both the Key Identifier and the Reset Key Identifier from the foreign SED. After both the old and new foreign keys are provided, the controller completes the key change that was in progress prior to the move and then execute the additional key change to import the foreign SEDs.
