Instructions

Once the customer receives the .lic file for Data Domain (DD) from the licensing team, the following steps must be performed for updating the license for DD or DDVE.  Latest license format DD is .xml.  After applying a .xml license file, the DD no longer accepts .lic license files.

Regenerate: The regenerate option re-creates any missing or out-of-sync license keys that are installed on the system. It also helps convert existing licenses to the new .XML license format. The process requires searching for existing licenses based on the system Locking ID. Specify system details and follow the steps provided. At the end of the process, the requested license key is available. Save the key to a file and use DDSM or the CLI to update your system license information.
The SLC documentation, available from Dell Software Licensing Central, provides additional information.

Using the Data Domain System Manager:

  1. Log in to the DD user interface with an admin account or limited admin role.
  2. Click Administration and then Licenses.
    • Click Add Licenses to add licenses from a license file.
    • If Licenses are already configured, Add Licenses is replaced with Replace Licenses.
    • Click Replace Licenses to replace or update the licenses already added.
  3. Browse to the .lic file and click Apply.

Using the Data Domain CLI:

  1. Open the .lic file on a text editor. Verify that all licenses for the system are put in a single file.
  2. Copy all the contents of the .lic file to your clipboard.
  3. Log in to the DD CLI with an admin account or limited admin role.
  4. Optionally, run # elicense update check-only to validate the ELMS license file content. Paste the contents of the license file and then press CTRL+D or CTRL+C to stop the command.
    • Note: This command validates the:
      • Signature
      • Feature name
      • Capacity values
      • Capacity units
      • Expiration date
  5. Update the ELMS license by running # elicense update. Paste the contents of the license file and then press CTRL+D or CTRL+C to stop the command.
  6. The licenses that are updated may be verified by running # elicense show all.
Note: Every time e-licenses are updated, the previous licenses are overwritten. Contact the Data Domain support team if assistance is required.
