# __stc_assertion_start
#
# ID: version_001_neg
#
# DESCRIPTION:
# Valid version values should be positive integers only.
#
# STRATEGY:
# 1) Form an array of invalid reservation values (negative and
# incorrectly formed)
# 2) Attempt to set each invalid version value in turn on a
# filesystem and volume.
# 3) Verify that attempt fails and the version value remains
# unchanged
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2007-06-27)
#
# __stc_assertion_end
