Example: crsctl trace check css
1.检查crs 状态
[oracle@rac01 ~]$ crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy
以上输出的crs css evm组件都是正常的，若有组件检查失败，
输出会给出以下Failure 信息：
[oracle@rac01 ~]$ crsctl check crs
Failure 1 contacting CSS daemon
Cannot communicate with CRS
Cannot communicate with EVM
2.检查crs各个组件的状态信息
检查cssd组件状态
[oracle@rac01 ~]$ crsctl check cssd
CSS appears healthy
检查crsd组件状态
[oracle@rac01 ~]$ crsctl check crsd
CRS appears healthy
检查evmd组件状态
[oracle@rac01 ~]$ crsctl check evmd
EVM appears healthy
3.用以下两条命令来维护crs服务的自动启动，需要用root用户执行
[root@rac01 ~]# /opt/ora10g/product/10.2.0/crs/bin/crsctl disable crs
[root@rac01 ~]# /opt/ora10g/product/10.2.0/crs/bin/crsctl enable crs
4.用root身份来停止crs服务
[root@rac01 ~]# /opt/ora10g/product/10.2.0/crs/bin/crsctl stop crs
Stopping resources.
Successfully stopped CRS resources
Stopping CSSD.
Shutting down CSS daemon.
Shutdown request successfully issued.
此时我们在rac01节点检查crs各个组件的状态会有以下的信息
[oracle@rac01 ~]$ crsctl check crs
Failure 1 contacting CSS daemon
Cannot communicate with CRS
Cannot communicate with EVM
rac02节点正常
[oracle@rac02 ~]$ crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy
5.用root身份来开启CRS服务
[root@rac01 ~]# /opt/ora10g/product/10.2.0/crs/bin/crsctl start crs
Attempting to start CRS stack
The CRS stack will be started shortly
此时系统正在启动CRS，我们来检查此时crs服务的状态，crs组件服务依次开启
只要所有组件状态都是healthy
[oracle@rac01 ~]$ crsctl check crs
CSS appears healthy
Cannot communicate with CRS
EVM appears healthy
[oracle@rac01 ~]$ crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy
6. 查看votedisk的信息
[oracle@rac01 ~]$ crsctl query css votedisk
0. 0 /dev/raw/raw1
located 1 votedisk(s).
