Editing DNS and DDNS settings

You can maintain host information centrally using DNS. You can use System Manager to add or modify the DNS domain name of your storage system. You can also enable DDNS on your storage system to update the name server automatically in the DNS server.

Before you begin

  • You must have set up a CIFS server or Active Directory account for the Storage Virtual Machine (SVM) for secure DDNS to work.
  • The DNS server administrator must have made the necessary changes in the DNS server for the DDNS functionality to work.

    Secure DDNS must be enabled on both Data ONTAP and in the DNS server.
