Synchronization
Synchronization is automatically applied to logical drives when they are created.
Synchronization recalculates the redundancy data to ensure that the working
data on the physical drives is properly in sync.
Mouse-over on the logical drive, click the View button, and look under Logical
Drive Information beside the line that says Synchronized. A Yes means the
logical drive was synchronized. See “Viewing Logical Drive Information” on
page 132.
