如何重新引导群集节点
如果您要关闭或重新引导群集中的其他活动节点，请至少等待您正在引导的节点处于登录提示状态之后进行。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。
步骤
-
SPARC：如果群集节点运行的是 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。
-
成为要关闭的群集节点上的超级用户。
-
使用 scswitch 和 shutdown 命令关闭群集节点。
在要关闭的节点上，输入以下命令。如果将 -i 6 选项和 shutdown 命令结合使用，将在关闭节点后重新引导节点。
# scswitch -S -h node # shutdown -g0 -y -i6
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。
-
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 -n
