Configuring Power Management (Sun Blades Only)

by Jeff Hunter, Sr. Database Administrator

Hard drive and system power management are adjustable with the dtpower application with Solaris 8 7/01 release and higher. However, the power management features were not present in Solaris 8 10/00 and Solaris 8 1/01 releases. By default, power management is enabled on all new Sun Blade systems. (I really wish Sun would change this!)

When the system is in low-power mode, the hard drive eventually spins down to conserve power. Later, when you perform a task that accesses the hard drive, the hard drive spins up again. You might have to wait a few seconds for the hard drive to spin up to full speed. If you find that the delay is inconvenient, you can turn off Energy Star power management using one of the two methods provided below:

Method #1

Method #2

The main configuration file for controller Power Management is /etc/power.conf.
