# ID: hotspare_detach_002_pos
#
# DESCRIPTION:
#	If a hot spare have been activated,
#	and invoke "zpool detach" with the original device,
#	then the hot spare will become a functioning device,
#	and automatically be removed from the list of available hot spares
#	then the spare is automatically removed once the replace completes.
#
# STRATEGY:
#	1. Create a storage pool with hot spares
#	2. Activate a spare device to the pool
#	3. Do 'zpool detach' with the original device
#	4. Verify the spare device will become a functioning device,
#		be removed from the list of available spares as well,
#		and the original drive will removed once replace completes.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING STATUS: COMPLETED (2006-06-07)
