向集群添加节点

创建集群后，可通过向其添加节点来进行扩展。一次只能添加一个节点。

1. 打开要添加到集群的节点的电源。

   结果

   节点将引导，然后在控制台上启动“集群设置”向导。

   Welcome to the cluster setup wizard.
   
   You can enter the following commands at any time:
     "help" or "?" - if you want to have a question clarified,
     "back" - if you want to change previously answered questions, and
     "exit" or "quit" - if you want to quit the cluster setup wizard.
        Any changes you made before quitting will be saved.
   
   You can return to cluster setup at any time by typing "cluster setup".
   To accept a default or omit a question, do not enter a value.
   
   By default, AutoSupport transmission is disabled.
   In order for this system to send event messages and periodic reports to Lenovo
   Technical Support, Autosupport data transmission needs to be enabled.
   To enable this feature, either enter "yes" to the following AutoSupport
   question, or enter the CLI command "autosupport modify -support enable"
   after cluster creation from the CLI. Please review the Lenovo Privacy
   statement at www.lenovo.com/privacy before enabling this feature.
   
   Enabling AutoSupport can significantly speed problem determination
   and resolution, should a problem occur on your system.
   
   To enable AutoSupport data transmission, type “yes”.
   Leave this field blank to keep data transmission disabled {yes, no} [no]:
   
   To continue with the cluster setup wizard, type "yes" {yes}:
   
   
2. 完成初始任务以继续按照集群设置向导进行操作：

   • 确认自动支持消息。请参阅用于管理自动支持的命令。

   • 通过按 Enter 键，将 e0M 保留为节点管理接口端口

   • 输入网络信息以在端口 e0M 上设置节点管理接口

   结果

   将退出节点设置向导，并显示登录提示，警告您尚未完成设置任务。

3. 按 Enter 键以使用命令行进入集群设置。
4. 提示创建新集群或加入现有集群时，请输入 join。

   示例

   Do you want to create a new cluster or join an existing cluster? {create, join}:
   join
   
5. 按照提示操作设置节点，并将其加入到集群：
   • 要接受提示的默认值，请按 Enter 键。
   • 要在出现提示时输入自己的值，请输入该值，然后按 Enter 键。
6. 对要添加的每个其他节点重复上述步骤。
