About configuring DNS settings

You can set a domain host name for each controller module to identify it for management purposes by configuring settings in the Domain Name Service (DNS) tab. The DNS name server supports IPv4 and IPv6 formats, and the system supports a maximum of three DNS servers per controller. Configuring the storage system to communicate with a DNS server within your network will allow network changes, such as frequent IP address changes in a DHCP environment, to occur without interrupting notifications sent by the system to users.

The controller will advertise the domain host name to DNS servers, and the DNS servers will in turn create and advertise a fully qualified domain name (FQDN) for the controller by appending the domain host name to the DNS domain string that identifies the controller.

A host name must differ for each controller, is not case sensitive, and can have from 1 to 63 bytes. The name must start with a letter and end with a letter or digit, and can include letters, numbers, or hyphens, but no periods.

After a reachable DNS server is configured on the system, you can configure an SMTP server using a name such as mysmtpserver.example.com. Further, you could configure search domain example.com and SMTP server mysmtpserver and reach the same destination.

You must use this feature to configure DNS parameters before you configure email parameters in any environments where DNS i be required to resolve server names. The system does not support auto-configuration of DNS parameters if network parameters are set to DHCP mode, so DNS must be manually configured regardless of the DHCP setting. For more information about configuring DNS settings, see Configure DNS settings.

If DNS server functionality is operational and reachable by the controller's nslookup service, the FQDN for each controller is also shown. If nslookup output is not available, the domain name will show '-'.
