Today's customers are changing production setup configurations for various reasons. These reasons include running low on IP addresses for a given subnet, management hostname updates, and DNS updates, among others. It is imperative for any product to be able to seamlessly transition between system configurations without affecting data integrity.
In PowerProtect Data Manager Appliance, customers can modify configuration parameters (such as the default management and data networks, DNS, NTP, time zone, and location settings) post-deployment without affecting data integrity.
Before changing configuration settings, consider the following guidance:
Note: The user does not need to be linked to the private network to change DNS settings, location, time zone, or NTP settings. Because DNS and NTP settings are nondestructive activities, they can be changed through the appliance management IP address.
Note: For information about how to perform a system reconfiguration, see the PowerProtect Data Manager Appliance DM5500 5.16.0.0 Administration Guide.
