Performing Appliance Reset
The NetScaler SDX appliance allows you to:
- Reset the configuration of the Appliance.
- Reset the Appliance to factory version
- Reset the Appliance to a particular Single Bundle Image version
Before performing an appliance reset, back up all the data stored on the appliance, including the settings of all the Citrix ADC instances provisioned on the appliance.
Citrix recommends that you store the files outside the appliance. Performing an appliance reset terminates all current client sessions with the Management Service, so you have to log back on to the Management Service for any additional configuration tasks. When you are ready to restore the data, import the backup files by using the Management Service.
The Management Service provides the following options to reset the Appliance:
- Config Reset
- Factory Reset
- Clean Install
