Administrator Guide

When an up and running standalone unit or stack is merged with another stack, based on election, the losing stack reloads and the master
unit of the winning stack becomes the master of the merged stack. For more details, see sectionsAdd Units to an Existing Stack and
Remove a Unit from a Stack. It is possible to reset individual units to force them to give up the management role or reload the whole stack
from the CLI to ensure a fully synchronized bootup.
