In Oracle Solaris 10, you administer power management by configuring the /etc/power.conf file and by using the pmconfig command. In Oracle Solaris 11, the poweradm command replaces the pmconfig command. Power administration in Oracle Solaris 11 includes a small number of controls that manage platform and implementation details. The poweradm command enables you to simplify power administration by manipulating a small number of controls. See poweradm(1M).
Review the following potential power management transition issues:
By default, suspend is not enabled on any system. To enable suspend and inspect this setting on systems that support this feature, use the poweradm command as follows:
# poweradm set suspend-enable=true # poweradm get suspend-enable
By default, the administrative-authority SMF service property of the poweradm command is set to the platform value. However, the power service goes into maintenance mode if the administrative-authority service property is set to the smf value before the time-to-full-capacity and time-to-minimum-responsiveness values have been set. If this problem occurs, you can recover as follows:
# poweradm set administrative-authority=none # poweradm set time-to-full-capacity= # poweradm set time-to-minimum-responsiveness= # svcadm clear power # poweradm set administrative-authority=smf
The GNOME power manager (GPM) feature, which runs when the GUI starts, changes the power management settings. This behavior is intentional to enable the integration of power management administration with GNOME Desktop behavior.
