 adding a "trace" argument at the very front.
 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).
