2.2 Cause
This is due to a failure of communicationbetween crsd.bin on nodes.
2.3 Solution
Check the network for the following items:
- Check to see that there is No firewall between the nodes
- Make sure that the MTU size is same.
- If MTU is larger than 1500, then the switch must be able to support largerMTU size.
- Make sure that you have disabled SELINUX
- Make sure that NICs are using full duplex and not auto negotiate.
- Misconfiguration on the switches will also cause this issue.
三．解决方法
在MOS的文档里提示的原因和防火墙，时间，SELINUX，网卡类型有关，基本可以确定就是和网卡相关的原因导致这类问题，我的的原因是是2个节点的网卡名称不一致，所以修改网卡名一致后，尝试重新执行一下root.sh 命令。
即修改之前：rac1 是eth0和eth1，节点2是：eth5和eth6. 怎么修改网卡名，这个google一下，这里不做说明。
卸载之前的操作，命令如下：
/u01/app/11.2.0/grid/crs/install/rootcrs.pl-deconfig -verbose -force
注意这里，Oracle11g与10g中命令的区别。
--卸载：
