当提示：

[root@localhost ~]# ipmitool sdr
Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No
such file or directory
Get Device ID command failed
Unable to open SDR for reading

需要添加如下：

[root@localhost ~]# modprobe ipmi_watchdog
[root@localhost ~]# modprobe ipmi_poweroff
[root@localhost ~]# modprobe ipmi_devintf
[root@localhost ~]# modprobe ipmi_si
[root@localhost ~]# modprobe ipmi_msghandler

当添加ipmi_si时，提示：

FATAL: Error inserting ipmi_si (/lib/modules/2.6.9-5.ELsmp/kernel/drivers/char/ipmi/ipmi_si.ko): No   such device

这是因为机器上没有IPMI设备而出现的报错。
