Configuring DNS settings

Configure domain names using DNS (Settings > Network > DNS) after setting the type of controller network ports to use (IPv4 and/or IPv6).

When configuring DNS settings, note the following:

• The system supports a maximum of three DNS servers per controller.
• DNS hostnames must differ for each controller, are 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.
• In the DNS Servers fields for each controller, specify up to three named server addresses that are recognized within your network to be queried by the DNS resolver. The resolver will query the network in the order listed until reaching a valid destination address. Any valid setting is treated as enabling DNS resolution for the system.
• In the DNS Search Domains fields for each controller, specify up to three domain names to search when resolving hostnames that are configured in the storage system. The resolver will query the network in the order listed until finding a match.
• To reset a hostname for a controller to its default setting, click the Reset Host Name button for that controller.
• To clear a DNS server or search domain for a controller, click for that setting.
• To clear all configured DNS servers and search domains for a controller, click the Clear DNS button for that controller. For more information about the DNS feature, see DNS settings.
