Managing the Redundancy License

The Hot Standby Redundancy requires a license. The license file specifies the MAC addresses of the Skylight orchestrator appliances for Site-A and Site-B.

Two commands allow you to manage the license for the redundancy feature:

• redundancy license import filename – Importing the license file with this command is the first step in configuring redundancy. If you do not import the license file, you will not be able to start redundancy.
• redundancy license reset – Use this command to uninstall the license. You should reset the license (that is uninstall it) before re-importing the existing license or importing a new license.

If you want to import a license, the license file must be present on the Skylight orchestrator appliance. See Copying the License File to Both Sites.

Replacing a License

Please follow the three sections below in sequence to complete this procedure.

To stop HA and config preferred site

The commands below must be done via AppMon on the active site only.

1. Stop the redundancy feature by entering:
   redundancy control stop

2. Config the preferred site (site-a or site-b) to ensure that this site remains the active site and to prevent the latest database loss on HA system when HA restarts:
   redundancy config preferred < site-a or site-b >

To reset and import a license

This procedure must be repeated in the console of the Skylight orchestrator appliance at both sites.

1. Check HA’s status again and ensure HA’s status is “Stopped” by entering:
   redundancy show status

   ---

   Note: if the HA’s status is “Started” on this site, stop HA again on this site by entering:
   redundancy control stop

   ---

2. Uninstall the license that is currently installed by entering:
   redundancy license reset

3. Import the license for the redundancy feature by entering:
   redundancy license import filename fullPath/licenseFilename

   Example of full path and filename: /data/drbd-proxy.license

To start HA again

The commands below must only be done via AppMon on the site of section I.

1. Start the redundancy feature by entering:
   redundancy control start

2. Ensure that redundancy is started by entering:
   redundancy show status

   The output should indicate that the global status is Started.
