#
# ID: zfs_snapshot_002_neg
#
# DESCRIPTION: 
#	"zfs snapshot -r" fails with invalid arguments or scenarios.
#	The invalid scenarios may include:
#	(1) The child filesystem already has snapshot with the same name
#	(2) The child volume already has snapshot with the same name
#
# STRATEGY:
#	1. Create an array of invalid arguments
#	2. Execute 'zfs snapshot -r' with each argument in the array, 
#	3. Verify an error is returned.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2006-06-19)
