# ID: zvol_swap_005_pos
#
# DESCRIPTION:
#	swaplow + swaplen must be less than or equal to the volume size.
#
# STRATEGY:
#	1. Get test system page size and test volume size.
#	2. Random get swaplow and swaplen.
#	3. Verify swap -a should succeed when swaplow + swaplen <= volume size.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2006-12-12)
