  31 # DESCRIPTION:
  32 #       'zpool add' works with nested replacing/spare vdevs
  33 #
  34 # STRATEGY:
  35 #       1. Create a redundant pool with a spare device
  36 #       2. Manually fault a device, wait for the hot-spare and then replace it:
  37 #          this creates a situation where replacing and spare vdevs are nested.
  38 #       3. Verify 'zpool add' is able to add new devices to the pool.
