+# DESCRIPTION:
+# 'zpool import' should import a pool with Errata #3 while preventing
+# the user from performing read write operations
+#
+# STRATEGY:
+# 1. Import a pre-packaged pool with Errata #3
+# 2. Attempt to write to the effected datasets
+# 3. Attempt to read from the effected datasets
+# 4. Attempt to perform a raw send of the effected datasets
+# 5. Perform a regular send of the datasets under a new encryption root
+# 6. Verify the new datasets can be read from and written to
+# 7. Destroy the old effected datasets
+# 8. Reimport the pool and verify that the errata is no longer present
+#
