#
# ID: snapshot_009_pos
#
# DESCRIPTION:
#	Verify 'snapshot -r' and 'destroy -r' can correctly create and destroy 
#	snapshot tree respectively.
#
# STRATEGY:
# 1. Use the snapshot -r to create snapshot for top level pool 
# 2. Verify the children snapshots are created correctly.  
# 3. Use destroy -r to destroy the top level snapshot
# 4. Verify that all children snapshots are destroyed too.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2006-06-20)
