Sun Cluster 3.0 12/01 系统管理指南

2.2.3 如何重新引导群集节点

  1. 如果群集节点运行的是 Oracle Parallel Server/Real Application Clusters，则应关闭数据库的所有实例。

    有关关闭过程，请参阅 Oracle Parallel Server/Real Application Clusters 产品文档。

  2. 成为要关闭的群集节点上的超级用户。

  3. 使用 scswitch 和 shutdown 命令关闭群集节点。

    在要关闭的节点上，输入以下命令。 如果结合使用 shutdown 命令 -i 6 选项，将使节点在关闭到 ok 提示符后重新进行引导。


    # scswitch -S -h nodelist
# shutdown -g0 -y -i6
    注意：

    群集节点必须具有到群集互连的有效连接才能获得群集成员的身份。

  4. 验证引导节点时未发生错误，而且节点现在处于联机状态。


    # scstat -n

2.2.3.1 示例 - 重新引导群集节点

以下示例显示了重新引导节点 physschost-1 时控制台所输出的内容。 群集中其他节点的控制台上也显示此节点的关闭和启动消息。


# scswitch -S -h phys-schost-1
# shutdown -g0 -y -i6
