35# DESCRIPTION:
36#	A snapshot already exists with the new name, then none of the
37#	snapshots is renamed.
38#
39# STRATEGY:
40#	1. Create snapshot for a set of datasets.
41#	2. Create a new snapshot for one of datasets.
42#	3. Using rename -r command with exists snapshot name.
43#	4. Verify none of the snapshots is renamed.
