Boot backupserver through IPMI, from the mainserver, once per week

[TallMan206]

Hi, 

 

I have a Dell R720 as Mainserver with UnRAID, and my Backupserver, a SuperMicro with IPMI, also with UnRAID (both running UnRAID 7 beta2).

I have a task where the mainserver once per week need to backup to the backupserver. 

My goal is do use the mainserver and let that connect to the IPMI to boot the server. I tried with backupserver in sleep, but it uses too much power and for the whole week using this power, it's not worth it.

 

Do you know a way to send a signal from the mainserver to the IPMI from the backupserver, making that machine boot?

I use a user script to power up some of my servers when I need to, e.g.:

 

#!/bin/bash
/usr/sbin/ipmipower -h 192.168.1.44 -u USER -p PASS -n

is Wake on lan not an option?

I'm using etherwake on a raspberry pi for Wake on LAN, works lovely for machines that are off, just make sure to enable it in the BIOS (usually under ACPI settings for PCI Express, or has been for my machines) and issue: sudo etherwake -i <interface name> <mac address of target>

Hope that helps.
