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。
