34# DESCRIPTION:
35# Verify 'zpool clear' can clear pool errors.
36#
37# STRATEGY:
38# 1. Create various configuration pools
39# 2. Make errors to pool
40# 3. Use zpool clear to clear errors
41# 4. Verify the errors has been cleared.
42#
43# TESTABILITY: explicit
44#
45# TEST_AUTOMATION_LEVEL: automated
46#
47# CODING_STATUS: COMPLETED (2006-08-10)
