Important
•
The Target array may require more disk drives than the
Source array.
• If the Target array requires an even number of disk drives but
the Source array has an odd number, add a disk drive as part
of the conversion process.
• You cannot reduce the number of disk drives in your array,
even if the Target array requires fewer disk drives than the
Source array.
