39# DESCRIPTION:
40# Verify 'zpool clear' can clear pool errors.
41#
42# STRATEGY:
43# 1. Create various configuration pools
44# 2. Make errors to pool
45# 3. Use zpool clear to clear errors
46# 4. Verify the errors has been cleared.
47#
48# TESTABILITY: explicit
49#
50# TEST_AUTOMATION_LEVEL: automated
51#
52# CODING_STATUS: COMPLETED (2006-08-10)
