ipmitool - can't find /dev/ipmi0 or /dev/ipmidev/0

  • 772

Based on a previous question, I installed ipmitool (yum install ipmitool).

Even after a reboot, though, i get the following error when trying to run ipmitool power status:

Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory
Unable to get Chassis Power Status

Is this an OS/hardware issue (CentOS 6.3 x64 on a hosted machine in a remote datacenter - unsure on hardware vendor)? Or have I missed something more elemental in installing ipmitool?

    You probably need to load the IPMI kernel modules:

    modprobe ipmi_devintf
modprobe ipmi_si

    You can add these to /etc/modules to have them loaded automatically (just list the module names):

    ipmi_devintf
ipmi_si

  2. Do you have the devices loaded ? You can load manually the modules : modprobe ipmi_devintf ; modprobe ipmi_si and check your logs

  3. Just wanted to highlight another minor point: "Make sure you are running with root/admin privileges".

    user@host:~$ ipmitool power status
Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory

user@host:~$ ls /dev/ipmi*
/dev/ipmi0

user@host:~$ lsmod | grep ipmi
ipmi_devintf           20480  0
ipmi_ssif              24576  0
ipmi_si                57344  0
ipmi_msghandler        49152  3 ipmi_ssif,ipmi_devintf,ipmi_si

user@host:~$ sudo ipmitool power status
