When initiated by the Array Configuration Utility, the Smart Array 431
automatically redistributes the data in the original logical drive to a logical
drive that spans all of the physical drives in the array, including the added
drives. The room left over is used to increase the size of a logical drive or
create additional logical drives, also spanning all physical drives. The
extended logical drive is within the larger drive array. When logical drives are
added, both logical drives are then included in the drive array with expanded
storage capacity. See Figure D-10.
