Updating a Key

Updating a Key

The key validity period is one year. Before the key expires, manually update the key of a self-encrypting disk domain to ensure security.


This operation can be performed only by the super administrator and security administrator.


  1. Log in to DeviceManager.
  2. Choose Provisioning > Disk Domain.
  3. Select the disk domain whose keys need to be updated and click Rekey.

    The Warning dialog box is displayed.

  4. Carefully read the contents. Then select I have read and understand the consequences associated with performing this operation and click OK.

    The Success dialog box is displayed.


    The Success dialog box only indicates that the key update operation is issued successfully. It takes several minutes for the system to update the keys for all SEDs (depending on the number of SEDs). After the update is complete, the system reports an event "succeeded in updating the key of self-encrypting disks in disk domain". If you want to perform other operations (for example, deleting the disk domain) after the update operation is issued, ensure that you perform these operations after the system has reported this event.

  5. Click OK.

Follow-up Procedure

After the self-encrypting disk domain is updated, export keys in time.
