CRS-0184: Cannot communicate with the CRS daemo的诊断

用户在重启服务器后，发现RAC中某节点无法查看RAC状态
查看RAC状态时报错
./crs_stat -t
CRS-0184: Cannot communicate with the CRS daemo
由于无法与crs通信，首先查看crs健康状况
[Oracle@oms bin]$ ./crsctl check crs
Failure 1 contacting CSS daemon
Cannot communicate with CRS
Cannot communicate with EVM
发现crs未启动，出现此问题可能和后台进程没有启动有关。

查看crs相关进程
[oracle@oms ~]$ ps -ef|grep crs

oracle 19184 19143 0 18:00 pts/1 00:00:00 grep crs
根据相关进程信息找到报错的日志痕迹，查看相关crs日志文件
[oracle@oms bin]$ cat /tmp/crsctl.5370
Failed 3 to bind listening endpoint: (ADDRESS=(PROTOCOL=tcp)(HOST=oms-priv))
根据上面提示联想多半是和网络配置有关，首先查看网络配置文件
[root@oms init.d]# ll /etc/hosts
-rw-r--r-- 2 root root 263 Dec 25 2011 /etc/hosts
检查这个文件并无权限光管问题
[root@oms init.d]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
