# ID: zpool_create_008_pos
#
# DESCRIPTION:
# 'zpool create' have to use '-f' scenarios
#
# STRATEGY:
# 1. Prepare the scenarios
# 2. Create pool without '-f' and verify it fails
# 3. Create pool with '-f' and verify it succeeds
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2007-08-17)
