# 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 ## 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. ## Tested Servers ### 1U Servers DL360p Gen8 ### 2U Servers DL380p Gen8 DL380p Gen9 DL80 Gen9 - Tested by @rootless4real SL4540 Gen8 - Tested by @YoSiJo ## 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 - [x] Create a Script to Install and Create fan control scripts - [x] Allow easier input of iLO parameters - [x] Make ESXI friendly version - Big thanks to @thomaswilbur for making the script and @TannerFilip for making the script easier to use! - [x] Add info about the security switch - [x] Allow users to input iLO parameters when using `install.sh` - [x] Make the install.sh script have fun colors :D - added thanks to @TannerFilip ### Links and other stuff Original Reddit post:
