如何在非群集模式下引导群集节点
您可以引导一个节点，不使其成为群集成员，即处于非群集模式。非群集模式在安装群集软件或执行某些管理过程（如修补一个节点）时有用。
步骤
-
成为要在非群集模式下启动的节点上的超级用户。
-
使用 scswitch 和 shutdown 命令关闭节点。
# scswitch -S -h node # shutdown -g0 -y -i0
-
检验节点是否显示 ok 提示符或在“当前引导参数”屏幕中显示 Select (b)oot or (i)nterpreter 提示。
-
将 boot(1M) 或 b 命令与 -x 选项结合使用，在非群集模式下引导节点。
-
SPARC：
ok boot -x
-
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 -x
该节点的控制台上显示的消息称该节点不是群集的一部分。

示例 3–13 SPARC: 在非群集模式下引导群集节点
以下示例显示了关闭节点 phys-schost-1 后在非群集模式下重新启动该节点时控制台所输出的内容。-g0 选项将宽延期设置为零，-y 表示在遇到确认问题时，自动回答 yes，而 -i0 则调用运行级 0（零）。群集中其他节点的控制台上也显示此节点的关闭消息。
