通过HPE iLO控制风扇转速

我最初尝试采用标准的 IPMI 方式来控制 HPE ProLiant DL360 Gen9服务器 风扇转速，目的是实现 无风扇服务器 。不过，HPE服务器的 ipmi 资料非常匮乏，我找不到 IPMI sensor和风扇转速 的HPE服务器配置方法( ipmitool raw 参数各个厂商不统一，没有资料无法配置 )。

从网上资料来看，HPE服务器的风扇控制是通过 HP服务器iLO技术 实现的，只是实现方法非常曲折

备注

我暂时还没有时间精力来尝试实践，这里只做资料汇总。过几天再搞…

脚本控制

HOW TO CONTROL HPE ILO FAN SPEED (ILO 4, GEN 8~9) 提供了一个封装脚本，通过 iLO 的SSH密钥方式来登陆 iLO 进行设置(其实就是 ssh 执行 iLO 命令)。脚本非常简单，但是可以看出设置方法。结合iLO手册，我觉得应该很容易完成。

备注

简单看了一下脚本，iLO设置看起来非常简单的命令。也就是 ssh服务 远程执行，使用密钥认证可以非常方便完成。

通过iLO远程命令调整服务器风扇转速
#!/bin/bash
#Script to reduce fan speeds on ilo4 remotely.
# Install new public key on ilo4 as described here:
# https://ouphe.net/2020/04/05/add-ssh-key-to-ilo4-user-for-authentication/
#HELPFUL INFO
# Use Putty or similar to login from Windows. Reset iLO (iLO > Info > Diagnostics) each time to view. Only first login can see any responses.
# Run "fan info" to get readout
