A Using Power Management

This appendix contains information about using power management (PM) on Oracle VM Server for SPARC systems.

Starting with the Oracle VM Server for SPARC 3.5.0.1 software, Logical Domains Manager-based PM is disabled by default for Oracle SPARC platforms.

To enable PM, set the ldmd/pm_enabled SMF property value to true. See the ldmd(8) man page.

If you do not plan to override this new default, perform the following steps before you upgrade to the Oracle VM Server for SPARC software. Performing these steps ensures that the system runs at full power and with the highest performance.

Perform the following steps that apply to your SPARC server:

• Up to and including the SPARC M6 and SPARC T5 series servers.

  1. Disable Service Processor power management, also known as the platform policy.

     Run the following ILOM command as an administrative user:

     --> set /SP/powermgmt/ policy=disabled

  2. Set the PM administrative control to platform on the control domain as superuser:

     primary# poweradm set active_control/administrative-authority=platform

• Starting with the SPARC M7, SPARC T7, and SPARC S7 series servers. Perform one of the following steps:

  • Perform a power cycle of the server.

  • Update the server with at least system firmware version 9.8.6.
