RAC 11g 心跳单网卡调整为双网卡

来源：互联网发布：2017年网络暴力案例编辑：程序博客网时间：2024/05/04 06:09

在日常维护中，由于各种情况需要对rac的网络进行调整譬如：网卡名字修改，网卡功能调整，公网业务网络、私网心跳单网卡转双网卡调整；本次测试将rac私网心跳由一个网卡转变为多个网卡进行通讯，使用到的结束rac haip的心跳技术来实现；当然也可以使用操作系统层面的bond、etherchanel等技术来实现；

步骤说明：

1、查看现在的网卡状态；

2、配置网卡ip：

3、添加haip ip；

4、重启集群软件（这里需要注意，需要两节点同时重启；如果只是启动crs，haip配置是无效的，如果是分别重启也是无效的，看官可以自行try it）；

实验步骤：

集群状态：

总结：

至此心跳haip添加完成；看官可自行对后续进行测试，ifdown端口后看网络是否漂移等进行确认

haip知识点请阅读官方文档：https://docs.oracle.com/cd/E11882_01/server.112/e10803/config_cw.htm#HABPT5279
