Sun Cluster 系统管理指南（适用于 Solaris OS）

群集关闭和引导概述

Sun Cluster scshutdown(1M) 命令按照顺序停止群集服务并完全关闭整个群集。在移动群集位置时可能会用到 scshutdown 命令。如果因应用程序错误造成数据损坏，也可以使用该命令。

注 –

请使用 scshutdown 命令，而不要使用 shutdown 或 halt 命令，以确保正确关闭整个群集。将 Solaris shutdown 命令与 scswitch(1M) 命令结合使用可以关闭各个节点。有关更多信息，请参见如何关闭群集或关闭和引导单个群集节点。

scshutdown 命令通过以下方式停止群集中的所有节点：

  1. 使所有正在运行的资源组脱机。

  2. 卸载所有群集文件系统。

  3. 关闭活动的设备服务。

  4. 运行 init 0，并使所有节点转到基于 SPARC 系统上的 OpenBootTM PROM ok 提示符下 ，或转到基于 x86 系统上的引导子系统中。有关引导子系统的详细说明，请参见《System Administration Guide: Basic Administration》中的“Boot Subsystems”。

注 –

根据需要，您可以在非群集模式下引导节点，使节点不成为群集成员。非群集模式在安装群集软件或执行某些管理过程时有用。有关更多信息，请参见如何在非群集模式下引导群集节点。

表 3–1 任务列表：关闭和引导群集

任务 

参考 

停止群集 

    - 使用 scshutdown(1M)

请参见如何关闭群集

通过引导所有节点来启动群集。 

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。 

请参见如何引导群集

重新引导群集 

    - 使用 scshutdown

在 ok 提示符或“当前引导参数”屏幕上的 Select (b)oot or (i)nterpreter 提示下，使用 boot(1M) 或 b 命令分别引导每个节点。

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。 

请参见如何重新引导群集

Procedure如何关闭群集

注意 – 注意 –

不要在群集控制台上用 send brk 来关闭群集节点。群集内部不支持该命令。

步骤

  1. SPARC：如果群集上运行的是 Oracle Parallel Server 或 Real Application Cluster，请关闭数据库的所有实例。

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

  2. 成为群集中任一节点上的超级用户。

  3. 立即关闭群集。

    从群集中的单个节点，键入以下命令。


    # scshutdown -g0 -y

  4. 检验在基于 x86 的系统上的引导子系统中或在基于 SPARC 的系统上的所有节点是否都显示了 ok 提示符。

    在基于 SPARC 的系统上或基于 x86 的系统的引导子系统上，所有群集节点都显示 ok 提示符后，才能关闭所有节点电源。

  5. 如有必要，关闭节点电源。

示例 3–1 SPARC: 关闭群集

以下示例说明了在停止正常的群集操作，并关闭所有节点，以使 ok 提示符被显示时控制台所输出的内容。-g 0 选项将关闭宽延期设置为零，而 -y 表示在遇到确认问题时，自动回答 yes。群集中其它节点的控制台上也显示关闭消息。

要重新启动已关闭的群集，请参见如何引导群集。

Procedure如何引导群集

步骤

  1. 要启动群集，其节点已关闭并处于 ok 提示符下或“当前引导参数”屏幕上的 Select (b)oot or (i)nterpreter 提示下，请针对每个节点使用 boot(1M)。

    如果在两次关闭操作之间进行了配置更改，则首先启动具有最新配置的节点。除上述情形外，节点的引导顺序无关紧要。

    • SPARC： 


      ok boot

    • x86： 


                            <<< Current Boot Parameters >>>
Boot path: /pci@0,0/pci8086,2545@3/pci8086,1460@1d/pci8086,341a@7,1/
sd@0,0:a
Boot args:

Type    b [file-name] [boot-flags] <ENTER>  to boot with options
or      i <ENTER>                           to enter boot interpreter
or      <ENTER>                             to boot with defaults

                  <<< timeout in 5 seconds >>>
Select (b)oot or (i)nterpreter: b

    激活群集组件时，已引导节点的控制台上将显示消息。

    注 –

    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。

  2. 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(1M) 命令可以报告节点的状态。


     # scstat -n
    注 –

    如果群集节点的 /var 文件系统已满，可能无法在该节点上重新启动 Sun Cluster。如果出现该问题，请参见如何修复已满的 /var 文件系统。

示例 3–3 SPARC: 引导群集

以下示例说明了将节点 phys-schost-1 引导到群集中时控制台所输出的内容。群集中其它节点的控制台上会显示类似的消息。

Procedure如何重新引导群集

运行 scshutdown(1M) 命令以关闭群集，然后在每个节点上使用 boot(1M) 命令引导群集。

步骤

  1. SPARC：如果群集运行的是 Oracle Parallel Server 或 Oracle 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 或 Oracle Real Application Clusters 产品文档。

  2. 成为群集中任一节点上的超级用户。

  3. 关闭群集。

    从群集中的单个节点，键入以下命令。


    # scshutdown -g0 -y

    将关闭所有节点。

    注 –

    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. 引导每个节点。

    节点的引导次序无关紧要，除非您在两次关闭操作之间进行了配置更改。如果在两次关闭操作之间进行了配置更改，则首先启动具有最新配置的节点。

    • SPARC： 


      ok boot

    • x86： 


                            <<< Current Boot Parameters >>>

Type    b [file-name] [boot-flags] <ENTER>  to boot with options
or      i <ENTER>                           to enter boot interpreter
or      <ENTER>                             to boot with defaults

                  <<< timeout in 5 seconds >>>
Select (b)oot or (i)nterpreter: b

    当群集组件被激活时，所引导的节点的控制台上将显示消息。

  5. 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 命令报告节点状态。


     # scstat -n
    注 –

    如果群集节点的 /var 文件系统已满，可能无法在该节点上重新启动 Sun Cluster。如果出现该问题，请参见如何修复已满的 /var 文件系统。

示例 3–5 SPARC: 重新引导群集

以下示例显示在停止了正常的群集操作，并关闭了所有节点，使其转到 ok 提示符下然后再重新引导群集时控制台所输出的内容。-g 0 选项将宽延期设置为零，而 -y 表示在遇到确认问题时，自动回答 yes。群集中其它节点的控制台上也显示关闭消息。
