fuelg command

This command displays power domain information, listing the power modules that are installed in the BladeCenter unit and information about how the power in each domain is used. This command also configures the power domain policies for power redundancy loss and limiting fan noise during thermal events.

Note: For scripting purposes, the -qm and -os fuelg options for management modules other than the advanced management module are supported by the advanced management module.
