Dynamic Capacity Expansion (DCE)

Dynamic Capacity Expansion (DCE) describes a modification operation used to increase the available free capacity on an array. The increase in capacity is achieved by selecting unassigned drives to be added to the array.

Once the capacity expansion is completed, additional free capacity is available on the array for creation of other logical drives. The additional free capacity can then be used to perform a Dynamic Logical Drive Expansion (DVE) on a standard or FlashCopy repository logical drive.

This modification operation is considered to be "dynamic" because you have the ability to continually access data on arrays, logical drives, and disk drives throughout the entire operation.
