Oracle 11gR2 RAC添加新节点错误之--IP子网掩码
系统环境：
操作系统：RedHat EL5
Cluster： Oracle GI(Grid Infrastructure)
Oracle： Oracle 11.2.0.1.0
如图所示：RAC 系统架构
对于Oracle 11G构建RAC首先需要构建GI(Grid Infrastructure)的架构
案例分析：
在Oracle 11gR2 RAC在添加新节点时，添加grid，在node3上执行root.sh时，出现以下错误：
[root@lxh4 ~]# /u01/11.2.0/grid/root.sh

一个重要的错误信息“2014-07-10 15:04:17.966: [ OCRAPI][3046512336]clsu_get_private_ip_addresses: no ip addresses found.”看来造成crsd启动失败的原因和private network interface 有关系
检查网络配置：

node3的private network interface的netmask 为255.255.255.0，和其他node的netmask（255.255.255.0）不一致！
解决方法：
1、修改node3的private network interface的netmask为255.255.255.0
2、清除crs的配置信息，重新执行root.sh
