I have SUSE Linux Enterprise 9 on an HP DL360 G3. Not long after the OS installation, I noticed that when I log into the server GUI, I get a message that appears briefly and says:
"The powersave daemon is not running or you are not a member of the powersave system group. Starting it will improve performance: /usr/sbin/rcpowersave start"
When I go to /user/sbin, I don't see a "rcpowersave" file - I do see "rcpowersaved" though (note the d at the end).
What I'm wondering is, what is HPs/the local guru's recommendation with regards to this on HP hardware?
Also, what are the drawbacks (if any) if I choose to implement this?
Thanks!
Solved! Go to Solution.

Even after I changed the POWERSAVE_CPUFREQD_MODULE to "off", as recommended by the errors in /var/log/messages (I don't want CPU scaling on this server).
Hmm....

It's a server.
If it's an activly used server, then having power-saving measures on it (for anything other than a screen, which should be turned *off* anyway (the ultimate in power-saving techniques!)) are redundant. You want the thing to *ROCK*.. Not save a few cents off your power bill.

Regardless, I won't lose sleep over it.

Pls disable powersaved daemon from chkconfig list , DL360g3 server runs well without it.
I did a small hpc cluster with such operation on all 8 nodes.
Good Luck,

SolutionTo turn off the powersaved service forever, execute the following steps:
1. #chkconfig --list|grep power
the screen will show you
hostname:~ # chkconfig --list|grep power
powersaved 0:off 1:off 2:on 3:on 4:off 5:on 6:off
powertweakd 0:off 1:off 2:off 3:off 4:off 5:off 6:off
It shows your powersaved will be started when the system startup to runlevel 3 and 5
2. #chkconfig powersaved off
this command will stop the powersaved daemon starting after next reboot.
3. re-run the first command to confirm you do turn off the powersaved service from the system service list.
4. #rcpowersaved stop to stop the powersaved service immediately.
Good Luck,

I still get that annoying message when I log on using the VNC GUI, however. Ah well - as long as the service isn't up, I'm ok with that.
