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
Minimum role manage
Syntax

[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.
