| # DESCRIPTION: |
| # A volume can be added as several segments, but overlapping segments |
| # are not allowed. |
| # |
| # STRATEGY: |
| # 1. Figure out three groups swaplow and swaplen. |
| # 2. Verify different volume segments can be added correctly. |
| # 3. Verify overlapping swap volume are not allowed. |
