+# DESCRIPTION:
+# Verify 'zpool status -e' only shows unhealthy devices.
+#
+# STRATEGY:
+# 1. Create zpool
+# 2. Force DEGRADE, FAULT, or inject slow IOs for vdevs
+# 3. Verify vdevs are reported correctly with -e and -s
+# 4. Verify parents are reported as DEGRADED
+# 5. Verify healthy children are not reported
+#
