Hi Frank,

​For your question, What should I do if I want to setup IPMI on my centos host?

1. Make sure your host hardware has BMC provided, typically a server does, but a PC or laptop won't, 
2. If so, use command "modprobe ipmi_si" or ipmi_devintf to load the kernel device driver for BMC
    If not, your host is not capable to setup IPMI becasue required hardware not exists

If loading kernel device successful, you won't see below error anymore when typing ipmitool in the bash
Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No
such file or directory

Hi all,

I am trying to load kernel module ipmi_si, while failed with error "No such
device", truth is I can find file in
../kernel/drivers/char/ipmi/ipmi_si.ko. So why I  can't load it?


# ls -l
-rwxr--r--. 1 root root 93080 Jul 23  2015

# modprobe ipmi_si
FATAL: Error inserting ipmi_si
No such device

# lsmod |grep ipmi
ipmi_devintf            7729  0
ipmi_poweroff           8532  0

ipmi_msghandler        38701  3 ipmi_devintf,ipmi_poweroff,ipmi_watchdog

# ipmitool
