#
# ID: hotspare_import_001_pos
#
# DESCRIPTION: 
#	If a storage pool has hot spare, 
#	regardless it has been activated or NOT,
#	invoke "zpool export" then import with this storage pool 
#	should runs successfully, and the data should keep integrity
#	after import.
#
# STRATEGY:
#	1. Create a storage pool with hot spares
#	2. Do 'zpool export' then 'zpool import' with following scernarios
#		- the hotspare is only in available list
#		- the hotspare is activated
#		- the hotspare is activated but offline
#		- the hotspare is activated but the basic vdev is offline
#	3. Verify the export/import runs successfully,
#		and the data keep integrity after import
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING STATUS: COMPLETED (2006-06-14)
