您还可以引导一个节点,使该节点不成为群集成员(即在非群集模式下)。 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。
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 提示或在“当前引导参数”屏幕中显示 Select (b)oot or (i)nterpreter 提示。
使用 boot(1M) 或结合使用 b 命令和 -x 选项在非群集模式下引导节点。
SPARC:
ok boot -x |
x86:

以下示例说明关闭节点 phys-schost-1、然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)。 群集中其它节点的控制台上也显示此节点的关闭消息。
