Sun Cluster 3.0 系统管理指南

2.1.2 如何引导群集

  1. 要启动一个其节点已全部关闭并已放在 ok PROM 提示符 下的群集，请引导每一个节点。

    除非在先后两次关闭之间更改了配置，否则各节点的引导次序无关紧要。如果在先后两次引导之间 更改了配置，则应当首先引导具有最当前配置的节点。


    ok boot

    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。

    注意：

    群集节点必须有到群集互联的工作连接，才能获得群 集成员的身份。

  2. 检验引导的节点是否存在错误及是否联机。

    scstat(1M) 命令报告节点的状态。


    # scstat -n

2.1.2.1 示例-引导群集

以下示例展示将节点 phys-schost-1 引导到群集中时的控制台 输出。群集中其他节点的控制台上会显示类似的消息。
