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