AIX安装RAC错误集锦（6）---网卡配置故障
环境：
操作系统： AIX 5.3.8
集群软件： CRS 10.2.0.1
数据库： Oracle 10.2.0.1
错误现象：
------“节点网卡信息不一致，在第二个节点运行root.sh 时，无法识别网卡”
节点1：aix211（en0 私有网络，en1 公共网卡）
节点2：aix212 （en0 私有网络，en2 公共网卡）

Invalid interface "en1" entered in an input argument.
解决方法：
在第二个节点上，以root用户运行vipca
--------------在en2 上绑定vip 地址
运行成功后，重新运行root.sh，问题解决！
# /u01/crs_1/bin/crs_stat -t

这种方法解决了安装时的vip故障，但在安装完后启动CRS的过程中又遇到了问题（详见《AIX安装RAC错误集锦（5）》），所以在规划时，尽量将所有节点en0 配置成public net，所有节点网卡一致！
