33#
34# DESCRIPTION:
35#	Verify 'snapshot -r' and 'destroy -r' can correctly create and destroy
36#	snapshot tree respectively.
37#
38# STRATEGY:
39# 1. Use the snapshot -r to create snapshot for top level pool
40# 2. Verify the children snapshots are created correctly.
41# 3. Use destroy -r to destroy the top level snapshot
42# 4. Verify that all children snapshots are destroyed too.
43#
44# TESTABILITY: explicit
45#
46# TEST_AUTOMATION_LEVEL: automated
47#
48# CODING_STATUS: COMPLETED (2006-06-20)
