3.4.5 如何從磁碟裝置群組移除節點（VERITAS 容體管理者）

請使用這個程序從執行 VERITAS 容體管理者（VxVM）之現有磁碟裝置群組（磁碟群組）移除叢集節點。

  1. 判斷其要移除之節點是其成員的磁碟裝置群組。


    # scstat -D

  2. 成為現行叢集成員節點的超級使用者（superuser）。

  3. 執行 scsetup 公用程式。


    # scsetup

    出現「主功能表」。

  4. 輸入 3（裝置群組與容體）來重新配置磁碟裝置群組。

  5. 輸入 5（從 VxVM 裝置群組移除節點）來從 VxVM 磁碟裝置群組移除節點。

    依提示從磁碟裝置群組移除叢集節點。將會詢問您以下項目的相關資訊：

    VxVM 裝置群組

    節點名稱

  6. 確認節點已從 VxVM 磁碟裝置群組移除：


    # scstat -D	
  ...
  Device group name: devicegroupname
  Device group type: VxVM
  Device group failback enabled: no
  Device group node list: nodename
  Diskgroup name: diskgroupname
  ...
