# ID: zpool_clear_004_pos
#
# DESCRIPTION:
# Verify 'zpool clear' can clear errors on spare devices.
#
# We don't need to check whether 'zpool clear' actually clears error counters.
# zpool_clear_001_pos will do that.  We just need to check that it doesn't
# return an error when used on a spare vdev.  This is really a test for whether
# zpool_find_vdev() from libzfs can work on a spare vdev.  Note that we're
# talking about he mirror-like "spare-0" vdev, not the leaf hotspare vdev.
#
# STRATEGY:
# 1. Create a pool
# 2. Activate a spare
# 3. Verify that "zpool clear" on the spare returns no errors
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2013-06-26)
