# __stc_assertion_start
#
# ID: checksum_001_pos
#
# DESCRIPTION:
# Setting a valid checksum on a pool, file system, volume, it should be 
# successful.
#
# STRATEGY:
# 1. Create pool, then create filesystem and volume within it.
# 2. Setting different valid checksum to each dataset.
# 3. Check the return value and make sure it is 0.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)
