power off during weekend

Linux and Unix-Like Linux
1

Hello,
I would like to turn off (mean no energy consumption) some servers during the weekend.
I would like to do it automatically so i thought to create macro commands to a shell client.The problem is that giving shutdown (shutdown -h now) the server(Sun X4200 M2) turn off but the fans are still working.Do you have any idea how to power off the element?

crontab the job.

shutdown -y -g0 -i5 should power off completely.

3

Have you tried running man shutdown (Linux) with the -P switch, or man poweroff (Linux) directly?

@Celtic_Monkey This works for Solaris OS but i am running also SLES.Sorry i didn't define that

@pludi I tried also this command with no result.

If i do this using crontab can i also power on the servers on Monday morning (for example) using crontab?

What version of SLES?

Sounds like you have an issue with ACPI or apm module?

have you tried forcing acpi?

Generally, computers don't do anything while they're off.

wake-on-lan is possible but that'd mean another computer on the same local network sticking around to send it the wake-up signal later. Sometimes you can find special timed wake-up options in the BIOS itself though.
