英业达OEM的双路EPYC服务器如何通过ipmitool控制风扇转速
本帖最后由 oldnetdog 于 2025-3-17 09:50 编辑有大神知道英业达的双路EPYC服务器怎么通过ipmitool工具调整风扇转速么？
机房里面有一台英业达给阿里云OEM的机器，开机风扇全速运转，进入系统也一样，风扇高达17000转，CPU和Nvme盘温度是极低，但声音如同飞机起飞，实在太响。
我看这个机器的产品代码叫做inventec horsea，似乎很多EPYC双路服务器都是类似的设计，包括国鑫的SR201系列。

问了下deepseek，给了以下操作建议，试了下也不行。
To control fan speeds on an Inventec Horsea server using ipmitool, follow these steps. Note: Exercise caution, as improper fan settings can lead to hardware damage. Always monitor temperatures closely.
1. Prerequisites
Ensure IPMI is enabled in the BIOS.
Install ipmitool on your system (Linux: sudo apt-get install ipmitool).
Have BMC credentials (defaults are often ADMIN/ADMIN; check Inventec docs).
2. Identify Fan Sensors
List all sensors to find fan IDs and current speeds:
ipmitool -I lanplus -H <BMC_IP> -U <USERNAME> -P <PASSWORD> sensor list | grep FAN
Replace <BMC_IP>, <USERNAME>, and <PASSWORD> with your BMC details.
3. Switch to Manual Fan Control
Inventec often uses OEM-specific raw commands. For many Inventec systems:
ipmitool -I lanplus -H <BMC_IP> -U <USER> -P <PASS> raw 0x3a 0x07 0x01
0x3a 0x07 0x01: Sets fan mode to manual.
4. Set Fan Speed
Use raw commands to adjust fan duty cycles (percentage). Example for 50% speed:
ipmitool -I lanplus -H <BMC_IP> -U <USER> -P <PASS> raw 0x3a 0x09 0x00 0x00 0x32
0x3a 0x09: OEM command for setting fan speed.
0x00: Fan ID (often 0x00 for all fans, 0x01 for specific zones).
0x32: Hex value for 50% (0x64 = 100%).
5. Revert to Automatic Control
ipmitool -I lanplus -H <BMC_IP> -U <USER> -P <PASS> raw 0x3a 0x07 0x00
Important Notes
Risk of Overheating: Manual control bypasses BMC safeguards. Monitor temps with ipmitool sensor.
Inventec-Specific Commands: The above raw commands (0x3a) are common for Inventec but may vary by model. Consult Inventec documentation if available.
Fan IDs: Experiment with 0x00, 0x01, etc., to target specific fans (test in a safe environment).
Troubleshooting
If commands fail, check BMC firmware version and update if necessary.
Community resources (e.g., GitHub, forums) may provide model-specific insights.
Always prioritize hardware safety and validate commands in a controlled setup.
执行ipmitool raw 0x3a 0x07 0x01
报错：
Unable to send RAW command (channel=0x0 netfn=0x3a lun=0x0 cmd=0x7 rsp=0xc1): Invalid command
请问有搞过这个服务器的大神么？
