Set controller DNS settings
The set controller DNSServers
command updates the Domain Name System (DNS) settings for a controller. DNS is used to resolve fully qualified domain names for the controllers and a Network Time Protocol (NTP) server.
Supported Arrays
This command applies to any individual storage array, including the E4000, E2700, E5600, E2800, E5700, EF600 and EF300 arrays, as long as all SMcli packages are installed.
Roles
To execute this command on an E4000, E2800, E5700, EF600, or EF300 storage array, you must have the Storage Admin role.
Context
Before you begin make sure that:
-
A DNS server is configured.
-
You know the addresses of a primary DNS server and a backup DNS server, in case the primary DNS server fails. These addresses can be IPv4 addresses or IPv6 addresses.
You need to send this command to both controllers. This command is controller-specific. |
If you already configured the array's management ports with DHCP (Dynamic Host Configuration Protocol), and you have one or more DNS or NTP servers associated with the DHCP setup, then you do not need to manually configure DNS/NTP. In this case, the array should have already obtained the DNS/NTP server addresses automatically. |
Syntax
set controller[a] DNSServers=(auto|(Address1 [Address2]))
