If the Deep Discovery Director (Internal Network Analytics Version) server is unresponsive or cannot be restored, it can be replaced by another server.

Host machine hardware, host machine software, and Deep Discovery Director (Internal Network Analytics Version) version and build of the replacement server must be the same as the active server.

  1. Back up the configuration settings and database of the active server.
    1. On the management console of the active server, go to Administration > System Maintenance > Back Up.
    2. Under Configuration Settings and Database Backup, click Export.

      The active server exports a backup file with the configuration settings and database.

    3. Download and save the backup file.
  2. Install Deep Discovery Director (Internal Network Analytics Version) on the replacement server.
  3. Configure temporary network addresses for the replacement server.
    Important:

    Verify that the temporary network addresses are different from the network addresses of the active server to avoid IP addressing conflicts.

  4. Log on to the management console of the replacement server.
  5. Restore the configuration settings and database on the replacement server.
    1. On the management console of the replacement server, go to Administration > System Maintenance > Restore.
    2. Click Select File... and select the backup file.
    3. Click Upload.

      The backup file is uploaded, and Deep Discovery Director (Internal Network Analytics Version) displays information about the backup file.

    4. Click Restore.

      Deep Discovery Director (Internal Network Analytics Version) displays a confirmation message.

    5. Click OK.

      Deep Discovery Director (Internal Network Analytics Version) restores configuration settings and database from the backup file, and then restarts the server.

  6. Restore the repository by re-uploading all previously uploaded update, upgrade, and Virtual Analyzer image files to the repository.
    Important:

    Update, upgrade, and Virtual Analyzer image files are not included in the backup file and are not restored automatically. Appliances cannot download and execute plans if the files are not re-uploaded to the repository.

  7. Power off the active server.
    1. On the management console of the active server, go to Administration > System Maintenance > Power Off / Restart.
    2. Click Power Off.

      The active server stops all services and gracefully shuts down.

      Warning:

      The replacement server will be configured to use the network addresses of the active server. Leaving the active server powered on will cause IP addressing conflicts.

  8. Configure the replacement server to use the network addresses of the active server.

    The replacement server is now ready to resume operation as the new active server.
