如何引导节点

如果要在全局群集或区域群集中关闭或重新引导其他活动节点，对于您要引导的节点，请等到多用户服务器里程碑进入联机状态。

否则，该节点将无法从群集中要关闭或重新引导的其他节点那里接管服务。

如果您在来宾域运行 Oracle Solaris Cluster，则重新引导控制域或 I/O 域会对运行的来宾域产生影响，包括使域停止运行。您应该将工作负荷重新调整到其他节点，并在重新引导控制域或 I/O 域前停止运行 Oracle Solaris Cluster 的来宾域。

重新引导控制域或 I/O 域时，来宾域不接收或发送心跳信号。这会导致发生记忆分裂和群集重新配置。由于控制域或 I/O 域已重新引导，来宾域无法访问任何共享设备。其他群集节点会阻止该来宾域访问共享设备。当控制域或 I/O 域完成重新引导后，来宾域上的 I/O 操作会继续进行，但任何针对共享存储的 I/O 都会导致来宾域出现紧急情况，因为在群集重新配置过程中已将其阻隔在共享磁盘之外。如果来宾使用两个 I/O 域实现冗余，同时一次仅重新引导一个 I/O 域，则可以缓解该问题。

phys-schost# 提示符表示全局群集提示符。此操作过程适用于全局群集。

此过程提供了 Oracle Solaris Cluster 命令的长格式。此外，大多数命令还有短形式。这些命令除了名称长短的不同以外，其功能都是相同的。

您还可以使用 Oracle Solaris Cluster Manager GUI 引导区域群集节点。有关 GUI 登录说明，请参见如何访问 Oracle Solaris Cluster Manager。

1. 要启动已关闭的全局群集节点或区域群集节点，请引导该节点。

   从全局群集的节点执行此过程中的所有步骤。

   • 在基于 SPARC 的系统上，运行以下命令。

     ok boot

   • 在基于 x86 的系统上，运行以下命令。

     显示 GRUB 菜单后，选择相应的 Oracle Solaris 条目，然后按 Enter 键。

     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。

   • 如果您具有区域群集，可以指定要引导的节点。

     phys-schost# clzonecluster boot -n node zoneclustername

2. 确认引导该节点时未发生错误，而且该节点现在处于联机状态。
   • 运行 cluster status 命令可报告全局群集节点的状态。

     phys-schost# cluster status -t node

   • 从全局群集中的节点运行 clzonecluster status 命令可报告所有区域群集节点的状态。

     phys-schost# clzonecluster status

     当托管区域群集节点的节点以群集模式引导时，区域群集节点只能以群集模式引导。

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