#
# DESCRIPTION:
#	If a hot spare is activated, 
#	and invoke "zpool replace" with this hot spare to another hot spare,
#	the operation should run successfully.
#
# STRATEGY:
#	1. Create a storage pool with multiple hot spares
#	2. Activate a hot spare by 'zpool replace' with the basic dev,
#		make sure there still have enough hot spare in available list.
#	3. Do 'zpool replace' with the hot spare to another AVAIL hot spare.
#	4. Verify the operation runs successfully.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING STATUS: COMPLETED (2006-06-07)
