如何停用节点

当置备操作失败时也请使用此过程。

1. 将节点设置为已删除状态。

   # ironic node-set-provision-state $NODE deleted

2. 显示节点的信息。

   在下面的示例中，具有星号 (*) 的属性指示节点的已删除状态。

   # ironic node-show $NODE

3. 如果要对失败的置备过程进行故障排除，请验证节点的字段。

   为节点指定的任何 driver_info 元素的问题都在 Reason 列下标识出来。

   # ironic node-validate $NODE
   +------------+--------+---------------+
   | Interface  | Result | Reason        |
   +------------+--------+---------------+
   | console    | None   | not supported |
   | deploy     | True   |               |
   | management | True   |               |
   | power      | True   |               |
   +------------+--------+---------------+
