Domain Name System (DNS) is used to resolve fully qualified domain names for the controllers and a Network Time Protocol (NTP) server. The management ports on the storage array can support IPv4 or IPv6 protocols simultaneously.
About this task
This procedure describes how to specify a primary and backup DNS server address. The backup DNS server can be optionally configured to use if a primary DNS server fails.
Note: If you already configured the storage array’s management ports with Dynamic Host Configuration Protocol (DHCP), and you have one or more DNS or NTP servers associated with the DHCP setup, then you do not need to manually configure DNS or NTP. In this case, the storage array should have already obtained the DNS/NTP server addresses automatically. However, you should still follow the instructions below to open the dialog box and make sure that the correct addresses are detected.
