HP-iLO-Fan-Control

Scripts are available for Linux and ESXi!

Allows a Simple Fan Curve to be set using the custom ROM made by u/phoenixdev on Reddit. (linked below)

This repo contains all the required files! :)

All you need to run is the commands below.

Currently using ILO4 Version 2.60 - Working on updating to 2.77 https://github.com/kendallgoto/ilo4_unlock

BEFORE PROCEEDING

READ SECURITY-SWITCH.MD, IT INCLUDES A LOT OF INFORMATION.

Installation

1. Switch iLO into maintenance mode, then reboot. (On the DL360 G8, this is located near the backplane connectors to the motherboard.)

2. Download the install.sh script and run it. This will download all required files and move them, installs the autofan.service, and downloads the correct autofan.sh based on your input ready to be edited. If you are an advanced user, you can install everything separately. (Download using wget https://raw.githubusercontent.com/That-Guy-Jack/HP-ILO-Fan-Control/main/Install.sh)

3. Run the prep.sh in the ilo_250 folder. If this errors, it may be because the iLO isn't it maintenance mode. (You may need to run this script as root. When flashing the fans spin up to 100%, so be prepared)

4. ./flash_ilo4 --direct

5. Once the flash has completed, shut down your system and unplug it. Make sure to switch iLO back out of maintenance mode.

6. Run systemctl daemon-reload and systemctl start autofan to activate the service.

7. Run systemctl enable autofan to start the service on reboot.

8. Enjoy silence! :) And if that’s too fast or too slow, edit autofan.sh to your needs.

Notes

• I recommend especially for the DL360 to add a small 40mm fan to the RAID controller to keep it cool.
• If you have the fan script working on a different server than what's listed in the tested server section, create an issue and I'll add it.

To-do

• Create a Script to Install and Create fan control scripts
• Allow easier input of iLO parameters
• Make ESXI friendly version - Big thanks to @thomaswilbur for making the script and @TannerFilip for making the script easier to use!
• Add info about the security switch
• Allow users to input iLO parameters when using install.sh
• Make the install.sh script have fun colors :D - added thanks to @TannerFilip
• Add features mentioned in #15
