# ID: zfs_rename_002_pos
#
# DESCRIPTION: 
#       'zfs rename' should successfully be capable of renaming
#       valid datasets back and forth multiple times.
#
# STRATEGY:
#       1. Given a file system, snapshot and volume.
#       2. Rename each dataset object to a new name.
#       3. Rename each dataset back to its original name.
#       4. Repeat steps 2 and 3 multiple times.
#       5. Verify that the correct name is displayed by zfs list.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-06-29)
