 /*
  * brief:
- * iterate the raid bdev config and add base bdevs to the raid bdev that
- * the config has. Skip nonexistent base bdev but stop iteration and
- * return failure if adding base bdev fails.
+ * Add base bdevs to the raid bdev one by one.  Skip any base bdev which doesn't
+ *  exist or fails to add. If all base bdevs are successfully added, the raid bdev
+ *  moves to the configured state and becomes available. Otherwise, the raid bdev
+ *  stays at the configuring state with added base bdevs.
  * params:
  * raid_cfg - pointer to raid bdev config
  * returns:
- * 0 - success
- * non zero - failure
+ * 0 - The raid bdev moves to the configured state or stays at the configuring
+ *     state with added base bdevs due to any nonexistent base bdev.
+ * non zero - Failed to add any base bdev and stays at the configuring state with
+ *            added base bdevs.
