ONTAP automatically discovers domain controllers through DNS. Optionally, you can add one or more domain controllers to the list of preferred domain controllers for a specific domain.
If a preferred domain controller list already exists for the specified domain, the new list is merged with the existing list.

To add to the list of preferred domain controllers, enter the following command:
vserver cifs domain preferred-dc add -vserver vserver_name -domain domain_name -preferred-dc IP_address, …+-vserver vserver_namespecifies the storage virtual machine (SVM) name.-domain domain_namespecifies the fully qualified Active Directory name of the domain to which the specified domain controllers belong.-preferred-dc IP_address,… specifies one or more IP addresses of the preferred domain controllers, as a comma-delimited list, in order of preference.
The following command adds domain controllers 172.17.102.25 and 172.17.102.24 to the list of preferred domain controllers that the SMB server on SVM vs1 uses to manage external access to the cifs.lab.example.com domain.
