#
# DESCRIPTION:
#       'zfs rename' should fail when this dataset was changed to an existed
#	dataset name or datasets are of different types.
#       For example, a filesystem cannot be renamed as a volume.
#
# STRATEGY:
#       1. Given a file system, snapshot and volume.
#       2. Rename each dataset object to a different type.
#       3. Verify that only the original name is displayed by zfs list.
#

# This array is a list of pairs:
#	item i: original type
#	item i + 1: new type
