环境：Cent0S 6.4 64bit、grid 64bit

自检出现“TCP connectivity of subnet”问题。

【问题】
手工进行grid自检，报出如下错误：
[grid@xzxt1 grid]$ ./runcluvfy.sh stage -pre crsinst -n xzxt1,xzxt2 -fixup -verbose

【解决】
[root@xzxt1 network-scripts]# vi ifcfg-eth0
--去掉GATEWAY=192.168.56.1
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.56.30
NETMASK=255.255.255.0

[root@xzxt1 network-scripts]# vi ifcfg-eth1
--去掉GATEWAY=10.10.10.1
DEVICE=eth1
ONBOOT=yes
BOOTPROTO=static
IPADDR=10.10.10.90
NETMASK=255.255.255.0

重启服务器后，再次自检此问题不再出现。

 

更改时间：2014年11月6日

纠错：

出现此现象后，生产环境下，不要对网关地址进行更改，出现此现象后，应该先检查时间是否同步，然后重启服务器即可解决问题。
