# ID: zpool_create_009_neg
#
# DESCRIPTION:
#	Create a pool with same devices twice or create two pools with same
#	devices, 'zpool create' should failed.
#
# STRATEGY:
#	1. Loop to create the following three kinds of pools.
#		- Regular pool
#		- Mirror
#		- Raidz
#	2. Create two pools but using the same disks, expect failed. 
#	3. Create one pool but using the same disks twice, expect failed.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-08-15)
