Creating a Key

Creating a Key

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

Prerequisites

A self-encrypting disk has been configured on the storage system. The AutoLock status of the self-encrypting disk is Disable.

If AutoLock Stateis 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 3-73.

    Figure 3-73 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. Set Encryption Type to Self-encrypting disk domain.
  6. Select the owning controller enclosure of the disks that constitute a disk domain, and set the Hot Spare Policy for the disk domain.

    • If you select Default settings, the storage system creates a disk domain using all disks owned by all controller enclosures.
    • If you select Manually select, you must manually select the owning controller enclosure.
    NOTE:

    You can create multiple disk domains.

  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 function pane, you can see that AutoLock is Enable.

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

    1. Log in to the key management server web interface as a group manager.
    2. Click the Keys tab.

      Figure 3-74shows the Keys tab page.

      Figure 3-74 Key management

    3. Set the filter as needed. In the result list, check whether a key has been generated based on the serial numbers of the disks in the disk domain, and whether the key is in the Active state.

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

Follow-up Procedure

After creating the self-encrypting disk domain, you can create LUNs to allocate the storage space to application servers. For details, see Basic Storage Service Configuration Guide of the corresponding product model.
