set dns-parameters


Description	Configures settings to resolve domain names using the Domain Name Service (DNS). 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. After a reachable DNS server is configured on the system, or if DHCP is enabled and a DHCP server is reachable, a DNS server may be automatically acquired. Otherwise, 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 command to configure DNS parameters before you configure email parameters in any environments where DNS will be required to resolve server names. The priority of DNS servers and search domains is: User-supplied, using this command DHCPv6 DHCPv4

Syntax	set dns-parameters [controller a\|b\|both] nameservers `nameserver-IP-list` [search-domains `domain-name-list`]
Parameters	controller a\|b\|both] Optional. Specifies whether to change controller A, B, or both. If this parameter is omitted, changes affect the controller being accessed. nameservers `nameserver-IP-list` An ordered list of name server addresses that are recognized within your network to be queried by the DNS resolver. You can specify a comma-separated list containing from one to three IPv4 or IPv6 addresses. The resolver will query the network in the order prescribed by the list until reaching a valid destination address. Any valid setting is treated as enabling DNS resolution for the system. search-domains `domain-name-list` Optional. An ordered list of domain names to search when resolving host names that are configured in the storage system. You can specify a comma-separated list containing from one to three domain names, with a maximum of 255 characters per domain name. The resolver will query the network in the order prescribed by the list until finding a match.
Examples	Configure the system to query the name server at IP address 8.8.8.8, or at 8.8.6.6 if 8.8.8.8 is unsuccessful or unreachable, to resolve any SMTP server name with a domain of gmail.com, followed by `google.com`, and finally by `yahoo.com`. # set dns-parameters nameservers 8.8.8.8,8.8.6.6 search-domains gmail.com,google.com,yahoo.com
