遇到crs_stat -t查看结果出现state 为unknow 的状态
安装的虚拟机，配置了10g rac 经常遇到crs_stat -t查看结果出现state 为unknow 的状态, 如下可以解决：
在root权限下进入../crs_1/bin目录下，执行
#./crsctl stop crs
#./crsctl start crs
此时可查看crs_stat -t，结果仍然为unknow;
执行
$crs_stop -all
$crs_start -all
此时多半会出现placement error的错误提示；
可以执行如下命令解决
其中红色标识的内容中关于srvctl命令执行的顺序为启动各个crs 资源的顺序，同时也可以作为停止某个rac节点的参考方法!
rac1->srvctl start listener -n rac1
rac1-> crs_stat -t
