# ID: zvol_swap_006_pos
#
# DESCRIPTION:
#	 A volume can be add as several segments, but overlapping 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.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2006-12-13)
