crsctl debug statedump css - dumps state info for css objects
crsctl debug log css [module:level]{,module:level}
- Turns on debugging for CSS
crsctl debug trace css - dumps CSS in-memory tracing cache
crsctl debug log crs [module:level]{,module:level}
- Turns on debugging for CRS

crsctl query crs softwareversion [<nodename>] - lists the version of CRS software installed
crsctl query crs activeversion - lists the CRS software operating version
crsctl lsmodules css - lists the CSS modules that can be used for debugging

Example: crsctl trace check css
1.檢查crs 狀態
[oracle@rac01 ~]$ crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy
以上輸出的crs css evm組件都是正常的，若有組件檢查失敗，
輸出會給出以下Failure 信息：
[oracle@rac01 ~]$ crsctl check crs
Failure 1 contacting CSS daemon
Cannot communicate with CRS
Cannot communicate with EVM
2.檢查crs各個組件的狀態信息
檢查cssd組件狀態
[oracle@rac01 ~]$ crsctl check cssd
CSS appears healthy
檢查crsd組件狀態
[oracle@rac01 ~]$ crsctl check crsd
CRS appears healthy
檢查evmd組件狀態
[oracle@rac01 ~]$ crsctl check evmd
EVM appears healthy
3.用以下兩條命令來維護crs服務的自動啟動，需要用root用戶執行
[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身份來停止crs服務
[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.
此時我們在rac01節點檢查crs各個組件的狀態會有以下的信息
[oracle@rac01 ~]$ crsctl check crs
Failure 1 contacting CSS daemon
Cannot communicate with CRS
Cannot communicate with EVM
rac02節點正常
[oracle@rac02 ~]$ crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy
5.用root身份來開啟CRS服務
[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
此時系統正在啟動CRS，我們來檢查此時crs服務的狀態，crs組件服務依次開啟
只要所有組件狀態都是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).
