# ID: zpool_import_002_pos
#
# DESCRIPTION:
# Verify that an exported pool cannot be imported
# more than once.
#
# STRATEGY:
#	1. Populate the default test directory and unmount it.
#	2. Export the default test pool.
#	3. Import it using the various combinations.
#		- Regular import
#		- Alternate Root Specified
#	4. Verify it shows up under 'zpool list'.
#	5. Verify it contains a file.
#	6. Attempt to import it for a second time. Verify this fails.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)
#
