Note: After RAID migration and capacity expansion, the expanded capacity for each virtual disk can be calculated
by the following formula: Expanded VD capacity
＝
(Original VD Capacity / Original Array Capacity) * Newly
Added Capacity of Hard Disk.
Example: The capacity of the original array is 2TB and two virtual disks exist under this array: VD1 (100GB) and
VD2 (200GB). If you migrate the array with a 1TB HDD, then after migration and expanding, the expanded VD1
capacity is 50GB, that is 50GB = (100GB/2TB)*1TB. And the expanded VD2 capacity is 100GB, that is 100GB =
(200GB/2TB)*1TB.
