setuname [-t] [-n node] [-s name]
The setuname utility changes the parameter value for the system name and node name. Each parameter can be changed using setuname and the appropriate option.
Either or both the -s and -n options must be given when invoking setuname.
The system architecture may place requirements on the size of the system and network node name. The command will issue a fatal warning message and an error message if the name entered is incompatible with the system requirements.
The following options are supported:
-n node Changes the node name. node specifies the new network node name and can consist of alphanumeric characters and the special characters dash, underbar, and dollar sign.
-s name Changes the system name. name specifies new system name and can consist of alphanumeric characters and the special characters dash, underbar, and dollar sign.
-t Temporary change. No attempt will be made to create a permanent change.

setuname attempts to change the parameter values in two places: the running kernel and, as necessary per implementation, to cross system reboots. A temporary change changes only the running kernel.
