Creating a Self-encrypting Disk Domain

Creating a Self-encrypting Disk Domain

After a self-encrypting disk domain is created on the storage system, an encryption key is automatically generated.

Prerequisites

SEDs have been configured on the storage system. The AutoLock status of the SEDs is OFF.

To query the AutoLock status of the SEDs, you can log in to the CLI of the storage system and run the show disk general command.

admin:/>show disk general  ID        Health Status  Running Status  Type  Capacity   Role       Disk Domain ID  Speed(RPM)  Health Mark  Bar Code              Item      AutoLock State      --------  -------------  --------------  ----  ---------  ---------  --------------  ----------  -----------  --------------------  --------  --------------

If AutoLock State is OFF, disk encryption is disabled.

Procedure

  1. Log in to DeviceManager.
  2. Choose Provisioning > Disk Domain.
  3. Click Create.

    The Create Disk Domain dialog box is displayed, as shown in Figure 3-41.

    Figure 3-41 Creating a disk domain

  4. Name and describe the disk domain.

    1. In Name, enter a name for the disk domain.
      NOTE:
      • Each disk domain has a unique name.
      • A disk domain name can contain only letters, digits, underscores (_), hyphens (-), and periods (.).
      • A disk domain name contains 1 to 31 characters.
    2. In Description, enter the usage and properties of the disk domain. The descriptive information helps identify the disk domain.

  5. In Encryption Type, select Self-encrypting disk domain.
  6. In Select controller enclosures, select the desired controller enclosure and specify the disk type and quantity.

    1. Set Controller Enclosure (Controller):
      • You can click to add an option for Controller Enclosure (Controller). A maximum of two options can be selected.
      • You can click to remove an option for Controller Enclosure (Controller). At least one option must be selected.
      NOTE:

      If you have created disk domains on two controller enclosures (controllers), the two are associated. Therefore, you cannot create new disk domains only on one of them.

    2. Set Disk Type and Quantity.
      1. Select the required disk types.
        NOTE:
        • You can select two disk capacity types for each disk domain.
        • When Encryption Type of a disk domain is set to Self-encrypting disk domain, you can only select a self-encrypting disk.
      2. Set Required Disks.
        NOTE:
        • When you set one value in Controller Enclosure (Controller), the number of required disks must be 8 or more.
        • When you set two values in Controller Enclosure (Controller), the number of required disks must be 16 or more and the entered number must be an even number.
    3. In Hot Spare Policy area, configure the hot spare policy for disk domain.

  7. Click OK.

    A message is displayed indicating that the operation succeeded.

  8. Click OK.

    After a disk domain is created, choose Provisioning > Disk Domain. In the lower pane, check that AutoLock of the SEDs in the disk domain is Enable.

  9. View the encryption key on the key management server.

    1. Log in to the key management server's web interface as an administrator.
    2. Choose Security > Keys.
      Figure 3-42 Key management
    3. Use the serial numbers of the SEDs in the disk domain to check whether the key has been generated in the key list, and whether the key is Active.

      You can run the show disk general disk_id= command and obtain the Serial Number of a disk from the command output.
