自檢出現“TCP connectivity of subnet”問題。
【問題】
手工進行grid自檢，報出如下錯誤：
[grid@xzxt1 grid]$ ./runcluvfy.sh stage -pre crsinst -n xzxt1,xzxt2 -fixup -verbose

【解決】
[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
重啟服務器后，再次自檢此問題不再出現。
