Users Guide

• The controller does not have any oine or missing virtual disks. If there are oine or missing virtual disks, ensure that you have a

backup of these virtual disks.

• Cables to any virtual disk are not disconnected.

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 Identier and the Passphrase.

Encryption Key Identier

An Encryption Key Identier is a user-supplied text label for the Passphrase. The identier 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.

NOTE: For more information on Encryption Key and Passphrase guidelines, click the icon on the Manage Encryption

Key page.

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 Identier.

An Encryption Key Identier 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 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.
