Flt Action] lets you determine the action of the adapter and connected drive if
communications are disrupted. By default, this parameter faults the drive. You can
set this parameter so that the drive continues to run. Precautions should be taken
to ensure that the setting of this parameter does not create a risk of injury or
equipment damage.
