#
# DESCRIPTION: 
#	If a vdev becomes degraded in a pool with a spare, the spare will be
#	activated.
#       
#
# STRATEGY:
#	1. Create 1 storage pools with hot spares.
#	2. Artificially degrade one vdev in the pool
#	3. Verify that the spare is in use.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING STATUS: COMPLETED (2012-08-06)
