启动oracle rac时，报如下错误

[root@capitek1 ~]# su - oracle
-bash-3.00$ srvctl start database -d capitek
PRKH-1010 : Unable to communicate with CRS services.
  [OCR Error(Native: prsr_initCLSS:[21])]
PRKO-2005 : Application error: Failure in getting Cluster Database Configuration for: capitek
-bash-3.00$ srvctl start database -d capitek
PRKH-1010 : Unable to communicate with CRS services.
  [OCR Error(Native: prsr_initCLSS:[21])]
PRKO-2005 : Application error: Failure in getting Cluster Database Configuration for: capitek
-bash-3.00$ crs_stat -t
CRS-0184: Cannot communicate with the CRS daemon.



处理方法：
1,在每个节点上：
/etc/init.d/init.crs stop
/etc/init.d/init.crs start

若crs进程正常，采用ps结果如下：
[root@capitek1 tmp]# ps -ef|grep crs

root     17951  4548  0 06:11 pts/1    00:00:00 grep crs
[root@capitek1 tmp]#


若crs进程有问题,结果如下：
[root@capitek1 tmp]# ps -ef|grep crs
root      3991     1  0 04:07 ?        00:00:00 /bin/sh /etc/init.d/init.crsd run
root      6818  4548  0 06:01 pts/1    00:00:00 grep crs
[root


2，查看/tmp下面的crsctl相关日志，发现是vote and ocs权限有问题，修正权限和所有权如下:

--ocr
chown root:oinstall  /dev/hdb1
chown root:oinstall /dev/raw/raw4
chmod 660 /dev/hdb1
chmod 660 /dev/raw/raw4

--voting disk
chown oracle:oinstall /dev/hdb2
chown oracle:oinstall /dev/raw/raw5
chmod 660 /dev/hdb2
chmod 660 /dev/raw/raw5


3,切换到oracle用户，利用srvctl正常启动rac

4,crs_stat -t查看rac各组件状态
