# ID: atime_002_neg
# 
# DESCRIPTION:
# When atime=off, verify the access time for files is not updated when read. 
# It is available to pool, fs snapshot and clone.
#
# STRATEGY:
# 1. Create pool, fs. 
# 2. Create '$TESTFILE' for fs.
# 3. Create snapshot and clone.
# 4. Setting atime=off on dataset and read '$TESTFILE'.
# 5. Verify the access time is not updated.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-11)
