Restoring from an FTP Server

Before you continue, take note of the following limitations with restoring a backup file of the controller network configuration from an FTP server:

1. Log on to the controller from the CLI. For more information, see the corresponding Command Line Interface Reference Guide for your controller platform.
2. At the prompt, enter en to enable privileged mode.

3. Enter show cluster-state to display the statuses of the node and the cluster.

   Before continuing to the next step, verify that both the node and the cluster are in service.

4. Enter the following command to log on to the FTP server and check for available backup files that can be copied to the controller:
   copy <ftp-url> backup-network
5. If multiple backup files exist on the FTP server, the CLI prompts you to select the number that corresponds to the file that you want to copy back to the controller.

   If a single backup file exists, the CLI prompts you to confirm that you want to copy the existing backup file to the controller.

   When the controller finishes copying the selected backup file from the FTP server back to the controller, the following message appears: Succeed to copy the chosen file from the remote FTP server

6. Enter show backup-network to verify that the backup file was copied back to the controller successfully.

7. Run restore network to start restoring the contents of the backup file to the current controller.

   The CLI displays a list of backup files, and then prompts you to select the backup file that you want to restore to the controller.

8. Enter the number that corresponds to the backup file that you want to restore.
   Figure 141  Enter the number that corresponds to the backup file that you want to restore
   

   

   
   

   The CLI displays the network configuration that the selected backup file contains.

   If the serial number of the current controller matches the serial number contained in one of the backup files, the CLI automatically selects the backup file to restore and displays the network configuration that it contains.

9. Type yes to confirm that you want to restore the selected backup file. The controller starts the restore process and performs the following steps:
   1. Stop all services.
   2. Back up the current network configuration.

      This will enable the controller to roll back to the current configuration, in case there is an issue with the restore process.

   3. Clean up the current network configuration.

   The controller deletes its previous network configuration, including static routes, name server, user defined interfaces, etc.

10. Restore the network configuration contained in the selected backup file.
11. Restart all services.

    When the restore process is complete, the following message appears on the CLI: All services are up!

12. Do the following to verify that the restore process was completed successfully:
    1. Run show cluster-state to verify that the node and the cluster are back in service.
    2. Run show interface to verify that all of the network configuration settings have been restored.
