Compaq AlphaServer GS60 Operation Manual page 303

When you do not specify a device name, LFU tries to update all devices.
LFU lists the selected devices to update and prompts before devices are updated.
In this next example, the -path option is used to update a device with different
firmware from the LFU default. A network location for the firmware file can be
specified with the -path option. In this example, the firmware filename is not a
valid file for the device specified.
CAUTION: Never abort an update operation. Aborting corrupts the firmware on
the module.
