# ID: zfsd_fault_001_pos
#
# DESCRIPTION: 
#   If a vdev experiences IO errors, it will become faulted.
#       
#
# STRATEGY:
#   1. Create a storage pool.  Only use the da driver (FreeBSD's SCSI disk
#      driver) because it has a special interface for simulating IO errors.
#   2. Inject IO errors while doing IO to the pool.
#   3. Verify that the vdev becomes FAULTED.
#   4. ONLINE it and verify that it resilvers and joins the pool.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING STATUS: COMPLETED (2012-08-09)
#
