37#
38# DESCRIPTION:
39#   'zpool scrub will scan spares as well as original devices'
40#
41# STRATEGY:
42#	1. Create a storage pool
43#	2. Add hot spare devices to the pool
44#       4. Replace one of the original devices with a spare
45#       5. Simulate errors on the spare
46#       6. Scrub the pool
47#       7. Verify that scrub detected the simulated errors
48#
49# TESTABILITY: explicit
50#
51# TEST_AUTOMATION_LEVEL: automated
52#
53# CODING STATUS: COMPLETED (2013-01-14)
