In Configure mode, you can create new
arrays, but you cannot modify existing arrays. The controller must
be connected to unassigned physical drives for this mode to be
available.
In Reconfigure mode, you can modify existing
arrays. For example, you can set up an array expansion, a logical
drive extension, or a migration. These procedures do not destroy
data, unless you specifically want the data to be deleted. In this
mode, ACU does not change an existing option setting unless you
specifically script a different value for that option.
