By setting up a Dynamic Domain Name Service (DDNS), you can further leverage DHCP to automatically make the DNS server in your network environment aware of the host names for all newly added Oracle ILOM systems using DHCP.
When DDNS is configured, network administrators can determine the host name of a specific Oracle ILOM SP or CMM by combining the product serial number with one of these prefixes: SUNSP or SUNCMMn. For example, given a product serial number of 0641AMA007, the host name for a server SP would be SUNSP-0641AMA007, the host name for a single chassis-installed CMM would be SUNCMM-0641AMA007, and the host names for two chassis-installed CMMs would be SUNCMM0-0641AMA007 and SUNCMM1-0641AMA007.
