dns modify

--id ID

Specifies the DNS configuration to modify.

--name NAME

Specifֶies a name for the DNS server configuration.

--vip VIP

Assigns a virtual IP to the DNS service. DNS requests from your external DNS server must be delegated to this IP.

--domain-suffix DOMAIN_SUFFIX

Specifies a suffix to append to domain names of each VIP pool. The suffix should complete each domain name to form a valid FQDN for DNS requests to target.

For example, if you have two VIP pools pool1 and pool2, you can set the domain name domain1 on pool1 and domain name domain2 on pool2 and the domain suffix to .vastdata.ourcorp.com. Requests for domain1.vastdata.ourcorp.com will be distributed among the VIPs in pool1 while requests for domain2.vastdata.ourcorp.com will be distributed among the VIPs in pool2.

--vip-gateway VIP_GATEWAY

If the external DNS server doesn't reside on the same subnet as the DNS VIP, include this option to specify the IP of a gateway through which to connect to the DNS server. The gateway IP must be on same subnet as the DNS VIP.

--enable|--disable

Enable or disable the DNS service.

--vip-subnet-cidr CIDR

Specifies the subnet, in CIDR format, on which the DNS VIP resides.

In CIDR notation, the subnet is expressed as the number of bits of each IP address that represent the subnet address.

For example, the subnet mask 255.255.0.0 is expressed as 16 in CIDR notation.

Specify only the trailing CIDR decimal number that indicates the subnet mask. e.g. If the DNS VIP is 192.0.2.3 and the CIDR subnet is 24, specify 24.

--vip-vlan VLAN

Specifies a VLAN. If your external DNS server is only exposed to a specific VLAN, include this option and specify the DNS server's VLAN to enable communication with the DNS server.
