You can maintain host information centrally by 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.
You must have set up a CIFS server or an Active Directory account for the storage virtual machine (SVM) for secure DDNS to work.
System Manager does not perform any validation checks for the DNS and DDNS settings.
