SPARC: Preconfiguring Power Management Information
You can use the Power Management software that is provided in the Solaris OS
to automatically save the state of a system and turn it off after
it is idle for 30 minutes. When you install the current Solaris
release on a system that complies with version 2 of the EPA's Energy
Star guidelines, for example a Sun4UTM system, the Power Management software is installed by
default. If you install with the Solaris installation program GUI, the installation program
prompts you to enable or disable the Power Management software. The Solaris text
installer prompts you to enable or disable the Power Management software after the
installation is complete and the system reboots.
Note - If your system has Energy Star version 3 or later, you are
not prompted for this information.
If you are performing interactive installations, you cannot preconfigure the Power Management information
and avoid the prompt. However, by using a custom JumpStart installation, you can
preconfigure the Power Management information by using a finish script to create an
/autoshutdown or /noautoshutdown file on the system. When the system reboots, the
/autoshutdown file enables Power Management and the /noautoshutdown file disables Power Management.
For example, the following line in a finish script enables the Power Management
software and prevents the display of the prompt after the system reboots.
Finish scripts are described in Creating Finish Scripts in Solaris Express Installation Guide: Custom JumpStart and Advanced Installations.
