Using the RACADM Command Line Interface 73
You can disable the DHCP for NIC address feature and specify a static IP
address, subnet mask, and gateway. For instructions, see "Setting Up Initial
Access to the CMC" on page 71.
NOTE: If you disable the DHCP for NIC address feature and then re-enable it later,
the static IP address, subnet mask, and gateway settings are lost.
Enabling or Disabling DHCP for DNS IP Addresses
By default, the CMC’s DHCP for DNS address feature is disabled. When
enabled, this feature obtains the primary and secondary DNS server addresses
from the DHCP server. Using this feature, you do not have to configure static
DNS server IP addresses.
To disable the DHCP for DNS address feature and specify static preferred and
alternate DNS server addresses, type:
racadm config -g cfgLanNetworking -o
cfgDNSServersFromDHCP
Setting Static DNS IP addresses
NOTE: These settings are not valid unless the DCHP for DNS address feature is
disabled.
To set the preferred DNS IP address, type:
racadm config -g cfgLanNetworking -o cfgDNSServer1
<IP-address>
To set the secondary DNS IP address, type:
racadm config -g cfgLanNetworking -o cfgDNSServer2
<IP-address>
Configuring DNS Settings
• CMC Registration. To register the CMC on the DNS server, type:
racadm config -g cfgLanNetworking -o
cfgDNSRegisterRac 1
NOTE: Some DNS servers will only register names of 31 characters or fewer.
Make sure the designated name is within the DNS required limit.
NOTE: The following settings are valid only if you have registered the CMC on
the DNS server by setting cfgDNSRegisterRac to 1.
