使用案例
检查crs状态
$ crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy
检查单个状态
$ crsctl check css
CSS appears healthy
启动crs栈，必须使用root用户
# ./crsctl start crs
Attempting to start CRS stack
The CRS stack will be started shortly
停止crs栈，必须使用root用户
# ./crsctl stop crs
Stopping resources.
Successfully stopped CRS resources
Stopping CSSD.
Shutting down CSS daemon.
Shutdown request successfully issued.
# ./crsctl disable crs
# ./crsctl enable crs
这个命令实际是修改了/etc/oracle/scls_scr/raw/root/crsstart这个文件里的内容。
查看votedisk磁盘位置
$ crsctl query css votedisk
0. 0 /dev/raw/raw2
located 1 votedisk(s).
增加votedisk
# ./crsctl add css votedisk /dev/raw/raw3 -force
Now formatting voting disk: /dev/raw/raw3
successful addition of votedisk /dev/raw/raw3.
删除votedisk
# ./crsctl delete css votedisk /dev/raw/raw4 -force
successful deletion of votedisk /dev/raw/raw4.
关于维护votedisk的相关内容可以查看笔者的如下博客

查看crs参数
$crsctl get css misscount
60
修改crs参数,必须为root用户
# ./crsctl set css miscount 60
跟踪crs模块，提供辅助功能
CRS由CRS，CSS，EVM三个服务组成，每个服务又是由一系列module组成，crsctl允许对每个module进行跟踪，并把跟踪内容记录到日志中。
$ crsctl lsmodules css
The following are the CSS modules ::
CSSD
COMMCRS
COMMNS
$ crsctl lsmodules evm
The following are the EVM modules ::
EVMD
EVMDMAIN
EVMCOMM
EVMEVT
EVMAPP
EVMAGENT
CRSOCR
CLUCLS
CSSCLNT
COMMCRS
COMMNS
跟踪CSSD模块，需要root用户执行：
# ./crsctl debug log css "CSSD:1"
Configuration parameter trace is now set to 1.
Set CRSD Debug Module: CSSD Level: 1
查看跟踪日志
# pwd
/u01/app/oracle/product/crs/log/rac1/cssd
# more ocssd.log
