In case the IPMI system on a Supermicro system is unresponsive, but you are still able to log into the main server, you can issue the following command(s) to reset the IPMI: # load the necessary modules (optional) sudo modprobe ipmi_si sudo modprobe ipmi_devintf # reset the IPMI sudo ipmitool mc reset cold # remove all the modules sudo rmmod ipmi_devintf sudo rmmod ipmi_si
