缘由

超微bmc里面的默认低ct的阈值有点高。如果你的静音风扇（例如猫扇），转速低了，就会强制触发全速，过会降下来，再依次反复。

操作-通过ipmitool更改风扇转速检测阈值

1. 准备一台电脑，以我的macbook为例。
2. 在你准备的电脑上安装ipmitool。brew install ipmitool
3. 使用ipmi命令来降低转速:

#我bmc的ip地址为192.168.50.132为例。所有风扇都配置一遍。
ipmitool -H 192.168.50.132 -U ADMIN -P ADMINPASSWORD sensor thresh FAN1 lower 0 100 125
ipmitool -H 192.168.50.132 -U ADMIN -P ADMINPASSWORD sensor thresh FAN2 lower 0 100 125
ipmitool -H 192.168.50.132 -U ADMIN -P ADMINPASSWORD sensor thresh FAN3 lower 0 100 125
ipmitool -H 192.168.50.132 -U ADMIN -P ADMINPASSWORD sensor thresh FAN4 lower 0 100 125
ipmitool -H 192.168.50.132 -U ADMIN -P ADMINPASSWORD sensor thresh FAN5 lower 0 100 125
ipmitool -H 192.168.50.132 -U ADMIN -P ADMINPASSWORD sensor thresh FANA lower 0 100 125
ipmitool -H 192.168.50.132 -U ADMIN -P ADMINPASSWORD sensor thresh FANB lower 0 100 125

得到反馈：

Locating sensor record 'FAN1'...
Setting sensor "FAN1" Lower Non-Recoverable threshold to 0.000
Setting sensor "FAN1" Lower Critical threshold to 100.000
Setting sensor "FAN1" Lower Non-Critical threshold to 125.000

修改后，进入你的bmc控制台查看你的风扇“低CT”值，是不是降低了？降低了就是成功了。

1. 修改bmc的 mac地址为 3CECEF72FC46

ipmitool -H host -U ADMIN -Ppassword lan set 1 macaddr 3C:EC:EF:72:FC:46

修改完成后，拔掉网线，重新插一下，使bmc重新获取新的Ip地址。

2. 使用下面的 license.lic

通过 ipmi界面上传这个授权文件。即可出现授权成功

激活成功后如下：
