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:
- Only releases 2.1 and later support restoring from an FTP server.
- In this current release, restoring the entire cluster from an FTP server is unsupported. The restore process must be performed on one node at a time.
- Restoring from an FTP server can only be
performed using the controller CLI.
Caution: Restoring a backup file to the controller requires restarting all of the controller services.
Follow these steps to restore a controller's network configuration using a backup file that you previously uploaded to an FTP server.
- Log on to the controller from the CLI. For more information, see the corresponding Logging In to the Controller CLI for your controller platform.
- At the prompt, enter the
enablecommand followed by the enable super-user password to enter Privileged EXEC mode. - Enter the command
show cluster-stateto ensure node and cluster statuses areIn servicebefore initiating this procedure. - Enter the command
copyftp-urlbackup-networkto log on to the FTP server and check for available backup files that can be copied to the controller: - 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.
- Enter
show backup-networkto verify that the backup file was copied back to the controller successfully. - Run the
restore networkcommand to start restoring the contents of the backup file to the current controller. - Enter the number that corresponds to the backup file that you want to restore.

[yes/no]
- Type yes to confirm
that you want to restore the selected backup file. The controller starts the
restore process and performs the following steps:
- Stop all services.
- 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).
- Clean up the current network configuration. The controller deletes its previous network configuration, including static routes, name server, user defined interfaces, and so on.
- Restore the network configuration contained in the selected backup file.
- Restart all services. When the restore process is complete, the following message appears on the CLI: All services are up!.
Please confirm this network setting, and this action will restart all services (or input 'no' to cancel)? [yes/no] yes Starting to stop all SmartZone services... All services are down. Make sure all other services are Online before any operations. Execute "#show service" to show other services. Starting to restore current system network setting... Starting to start all SmartZone services...
- Verify that the restore process was completed successfully:
You have completed importing and applying the network configuration backup from the FTP server to the controller.
