DR Scenario: Testing the DR Environment

Follow these steps to test the disaster recovery environment.
Before you make the backup server the new production server, ensure the original production server is down (not live). If you make the backup server the new production server while the original production server is still live, you can experience significant issues.
After finish testing the failover scenario (backup environment), you need to revert the server to its original state, which you can do through the UI or by modifying the configuration file.
  1. If you want to use Cortex XSOAR to backup the server, do the following:
    1. On the live production server, select
      Settings
      Advanced
      Backups
      Switch Hosts
      .
    2. When prompted, complete the online
      Switch Hosts
      instructions.
      Ensure that the production server is not live.
    3. Go to the backup server and follow the on-screen instructions:
    4. In the backup server environment, go to
      Settings
      About
      Troubleshooting
      .
    5. For the External Host Name key, update the value to the host name of the backup server (the new production server).
      The backup server is unaware of its external host name.
      After a successful switch, the backup server is now live.
  2. If you want to use a configuration file to test the DR environment, do the following:
    1. In the backup server, stop the server by typing:
      sudo service demisto stop
    2. Open the
      /etc/demisto.conf
      file and change the
      Server.dr.enabled
      property to
      false
      .
    3. In the live server, open the
      /etc/demisto.conf
      file and change the
      Server.dr.enabled
      property to
      true
      .
    4. Access the backup server using its IP address to check that the server is up and running.
  3. To revert to the original settings, repeat the steps above.
    When following the instructions, remember the backup server is now the production server and production server is now the backup server.
