You'll still need to run the System Configuration Utility and the Array Configuration Utility , where the controller will read the configuration information from the drives .

If we replace with the same controller will the SO and other data be safe? or do we need to configure the smart array controller? We have 3200 controller and we will replace with the same controller ? We do not want to lose the data?
