The Linux OpenIPMI driver is often loaded via the /etc/init.d/ipmi setup script. If your distribution/environment does not have this script, the following script can be used to load/unload the driver. #!/bin/sh /sbin/modprobe ipmi_devintf maj=`cat /proc/devices | awk '/ipmidev/{print $1}'` if [ -c /dev/ipmi0 ] then rm -f /dev/ipmi0 /bin/mknod /dev/ipmi0 c $maj 0 else /bin/mknod /dev/ipmi0 c $maj 0 fi /sbin/modprobe ipmi_si # do stuff /sbin/rmmod ipmi_si /sbin/rmmod ipmi_devintf /sbin/rmmod ipmi_msghandler
