+# DESCRIPTION:
+# 'zpool add -n <pool> <vdev> ...' can display the configuration without adding
+# the specified devices to given pool
+#
+# STRATEGY:
+# 1. Create a storage pool
+# 2. Use -n to add devices to the pool
+# 3. Verify the devices are not added actually
+# 4. Add devices to the pool for real this time, verify the vdev tree is the
+#    same printed by the dryrun iteration
