Disabling Power Management on Solaris
Topic: Solaris Posted:2003-12-25

We have a Sun box that displays "Saving system state... Please wait..." overnight. Well, this is the power management kicking in. Not happy with servers, so we need to disable this. The behavior of the power management service is set in /etc/power.conf. We can disable the automatic shutdown by editing this file.

Change:

autoshutdown            30              9:00 9:00               shutdown

To this:

autoshutdown            30              9:00 9:00               noshutdown

Probably a better way to deal with this is to simply disable the service completely:

# mv /etc/rc2.d/S85power /etc/rc2.d/s85power

Let's see what is running:

# ps -ef | grep powe
root   246     1  0   Dec 20 ?        0:00 /usr/lib/power/powerd
root  1140  1111  0 01:46:05 pts/1    0:00 grep powe
#

Let's reboot, and make sure our system doesn't start the service again:

# ps -ef | grep powe
root   376   374  0 01:55:13 pts/1    0:00 grep powe
#
