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