You can configure your storage system to use one or more DNS servers for host-name resolution. You can configure DNS by first creating or editing the /etc/resolv.conf file, then specifying the DNS domain name, and finally enabling DNS through the command-line interface.
Steps
- Depending on whether you want to create or edit the /etc/resolv.conf file, perform the following step:

Creating the /etc/resolv.conf file |
By using a text editor, create the /etc/resolv.conf file in the root volume. The file can consist of up to three lines, each specifying a name server host in the following format: nameserver ip_addressip_address is the IP address of the DNS name server. The IP address can be an IPv4 or an IPv6 address.
Note: If an IPv6 link-local address is specified as a DNS name server, the address must be appended with %interface_name. The appended interface_name is the name of the interface on the storage system that is connected to the same link as the specified DNS name server. For example: nameserver 2001:0db8::85a3:0:0:8a2e:0370:99 e0a is the interface on the storage system that is connected to the same link as the DNS name server with the IPv6 address 2001:0db8::85a3:0:0:8a2e:0370:99.

Editing the /etc/resolv.conf file |
From a workstation that has access to the root volume of your storage system, edit the /etc/resolv.conf file using a text editor. |
- Enter the following command to specify the DNS domain name:
options dns.domainname domain domain is the new domain name, which follows the host name of your storage system in the fully qualified domain name.
- Enter the following command to enable DNS:
options dns.enable {on|off} on—Enables DNS
off—Disables DNS
