38# DESCRIPTION:
39#   If an active hotspare experiences checksum errors, it will become degraded.
40#
41#
42# STRATEGY:
43#   1. Create a storage pool with a hotspare.  Only use the file vdevs because
44#      it is easy to generate checksum errors on them.
45#   2. fault a vdev to active the hotspare
46#   3. Mostly fill the pool with data.
47#   4. Corrupt it by DDing to the hotspare's underlying file.
48#   5. Verify that the hotspare becomes DEGRADED.
49#   6. ONLINE it and verify that it resilvers and joins the pool.
50#
51# TESTABILITY: explicit
52#
53# TEST_AUTOMATION_LEVEL: automated
54#
55# CODING STATUS: COMPLETED (2014-05-13)
