系统环境：
OS: Linux EL5
CRS： CRS 10.2.0.1
Oracle：Oracle 10.2.0.1
1、crs 启动失败
[root@node2 ~]# crsctl check crs
Failure 1 contacting CSS daemon
Cannot communicate with CRS
Cannot communicate with EVM
2、查看系统日志
[root@node2 ~]# tail /var/log/messages

[root@node2 ~]# cat /tmp/crsctl.3172
OCR initialization failed accessing OCR device: PROC-26: Error while accessing the physical storage Operating System error [Permission denied] [13]
[root@node2 ~]#
3、ocr 对应的裸设备权限出错
[root@node2 ~]# ls -l /dev/raw
total 0
crw------- 1 root root 162, 1 Nov 2 09:41 raw1
crw------- 1 root root 162, 2 Nov 2 09:41 raw2
[root@node2 ~]#
4、修改raw 权限配置文件，系统启动时自动应用权限
[root@node2 ~]# cat /etc/udev/rules.d/65-raw-permissions.rules
# Set permissions of raw bindings to Oracle Clusterware devices
KERNEL=="raw1", OWNER="oracle", GROUP="dba", MODE="660"
KERNEL=="raw2", OWNER="oracle", GROUP="dba", MODE="660"
[root@node2 ~]#
5、重新启动udev 服务
[root@node1 rules.d]# start_udev
Starting udev: [ OK ]
[root@node1 rules.d]# ls -l /dev/raw
total 0
crw-rw---- 1 oracle dba 162, 1 Nov 2 09:55 raw1
crw-rw---- 1 oracle dba 162, 2 Nov 2 09:55 raw2
[root@node1 rules.d]#
6、重新启动crs ，系统正常
[root@node2 ~]# crsctl stop crs
Stopping resources.

[root@node2 ~]# crsctl start crs
