Starting with the Oracle VM Server for SPARC 3.5.0.1 maintenance update release, the Power Management (PM) feature is disabled by default on Oracle SPARC systems. You can enable this feature by changing the ldmd/pm_enabled SMF property value to true.
Although the ldmd/pm_enabled SMF property was introduced in the Oracle VM Server for SPARC 3.5 release, be sure to install the Oracle VM Server for SPARC 3.5.0.1 maintenance update if you want to set this property value to false.
To disable PM manually, run the following commands:
primary# svccfg -s ldmd setprop ldmd/pm_enabled=false primary# svcadm refresh ldmd primary# svcadm restart ldmd
To enable PM manually, run the following commands:
primary# svccfg -s ldmd setprop ldmd/pm_enabled=true primary# svcadm refresh ldmd primary# svcadm restart ldmd
Note that the ldmd/pm_enabled SMF property applies only to Oracle SPARC systems. The PM functionality remains enabled by default on Fujitsu SPARC systems and is controlled by the ldmd/fjpm_enabled SMF property.
The following description of the ldmd/fjpm_enabled has been added to the ldmd(1M) man page:
Enables or disables Power Management (PM) at ldmd startup on Fujitsu SPARC systems. The default value is true, which means that PM is enabled.
The first time you set the property after installing the Oracle VM Server for SPARC 3.5.0.1 maintenance update, specify the boolean data type to ensure that the ldmd/fjpm_enabled SMF property is added to the SMF manifest. For example, the following command disables PM on a Fujitsu SPARC system:
primary# svccfg -s ldoms/ldmd setprop ldmd/fjpm_enabled=boolean: false
