ironic.drivers.modules.ipmitool module

IPMI power manager driver.

Uses the ‘ipmitool’ command (http://ipmitool.sourceforge.net/) to remotely manage hardware. This includes setting the boot device, getting a serial-over-LAN console, and controlling the power state of the machine.

NOTE THAT CERTAIN DISTROS MAY INSTALL openipmi BY DEFAULT, INSTEAD OF ipmitool, WHICH PROVIDES DIFFERENT COMMAND-LINE OPTIONS AND IS NOT SUPPORTED BY THIS DRIVER.
