[root@UNID02 bin]#
咨询系统工程师，告知这台机器之前Public IP使用的是eth0网卡，后来eth0网卡发生了故障，切换到了eth2网卡，原来如此。
有2个解决方法：
1.将unid01-vip修改为eth2
[root@UNID02 ~]$ srvctl modify nodeapps -n unid01 -A 10.0.15.175/255.255.255.0/eth2
再次启动，启动成功。
[oracle@UNID02 ~]$ crs_start ora.unid01.vip
Attempting to start `ora.unid01.vip` on member `UNID02`
Start of `ora.unid01.vip` on member `UNID02` succeeded.
2.因为crs_start会调用racgvip这个脚本启动vip，所以直接修改环境变量，再直接执行sh racgvip start ora.unid01.vip
[root@UNID02 ~]# export _USR_ORA_VIP=10.0.15.175
[root@UNID02 ~]# export _USR_ORA_NETMASK=255.255.255.0
[root@UNID02 ~]# export _USR_ORA_IF=eth2
[root@UNID02 ~]# export _CAA_NAME=ora.unid01.vip
[root@UNID02 bin]# sh -x racgvip start ora.unid01.vip
