41# DESCRIPTION:
42#	 A volume can be add as several segments, but overlapping are not
43#	 allowed.
44#
45# STRATEGY:
46#	1. Figure out three groups swaplow and swaplen.
47#	2. Verify different volume segments can be added correctly.
48#	3. Verify overlapping swap volume are not allowed.
49#
50# TESTABILITY: explicit
51#
52# TEST_AUTOMATION_LEVEL: automated
53#
54# CODING_STATUS: COMPLETED (2006-12-13)
