Configuring DNS Server Settings

Auto DNS through DHCP is enabled by default. However, you can manually configure DNS Name Servers and DNS Search Paths. To change DNS server information on the service processor, see the following procedures:

Configure DNS Server Settings on the SP (Oracle ILOM)

  1. Ensure that you have Admin (a) role privileges in Oracle ILOM.
  2. To configure DNS server information from the Oracle ILOM web interface:
    1. Log in to the Oracle ILOM web interface.
    2. In the navigation pane, click ILOM Administration → Connectivity, and click the DNS tab.
    3. To enable Oracle ILOM to automatically retrieve DNS information from a DHCP server on the network, select the Enabled check box.
    4. If you did not enable Auto DNS via DHCP, enter one or more DNS server IP addresses and search paths.
    5. Enter the DNS Timeout as an integer between 1 and 10.
    6. Enter the DNS Retries as an integer between 0 and 4.
    7. Click Save.
  3. To configure DNS server information from the Oracle ILOM command-line interface (CLI):
    1. Log in to the Oracle ILOM CLI.
    2. To enable Oracle ILOM to automatically retrieve DNS information from a DHCP server on the network, type the set command:

      set /SP/clients/dns auto_dns=enabled

    3. If auto_dns is disabled, set one more name servers and search paths:

      set /SP/clients/dns nameserver=ip_address_1,ipaddress_2,ipaddress_3 searchpath= domain_1.com,domain_2.edu,and so on

      You can specify up to three IP addresses and up to six search paths.

    4. Set the DNS timeout and retries:

      set /SP/clients/dns timeout=timeoutInSeconds retries=retries

      Where timeout is an integer between 1 and 10, and retries is an integer between 0 and 4.

    For more information, refer to Modifying Default Connectivity Configuration Properties, Oracle ILOM Administrator's Guide for Configuration and Maintenance, Firmware Release 5.0 at Systems Management Documentation.

Configure DNS Server Settings on the SP (Oracle Hardware Management Pack)

  1. Access the operating system command line with root privileges.
  2. To enable Oracle ILOM to automatically retrieve DNS information from a DHCP server on the network, type the following command:

    ilomconfig modify dns --autodns enabled --retries retries --timeout timeout

    Where timeout is an integer between 1 and 10, and retries is an integer between 0 and 4.

  3. If you prefer to disable autodns, type the following command:

    ilomconfig modify dns --nameservers nameserverlist --autodns disabled --retries retries --searchpath searchpathlist --timeout timeout

    For details, refer to Configuring Oracle ILOM (ilomconfig), Oracle Hardware Management Pack Server CLI Tools User's Guide at Systems Management Documentation.
