33# DESCRIPTION:
34# 'zpool add -n <pool> <vdev> ...' can display the correct configuration
35#
36# STRATEGY:
37# 1. Create different storage pools, use -n to add devices to the pool and
38#    verify the output is as expected.
39# 2. Create a pool with a hole vdev and verify it's not listed with add -n.
