Define the host name. The domain name is optional.
Note: The hostname will be used in TCP/IP communications between the
HMC and the LPARs on the public network. It is, therefore, important to ensure
a consistent naming convention: all LPARs, and the HMC, must use either
short-names (hostname only) or long-names (fully qualified domain name)
plus the domain name. If you are using DNS, then a fully qualified domain
name must be used.
