 查看一下表决磁盘和ocr的信息：
 [root@rac1 bin]# pwd
 /u01/app/11.2.0/grid/bin
 [root@rac1 bin]# ./crsctl query css votedisk
 ##  STATE    File Universal Id                File Name Disk group

查看当前ocr备份情况，ocr
[root@rac1 bin]# ./ocrconfig -showbackup
 
rac2    2014/03/25 12:04:28    /u01/app/11.2.0/grid/cdata/rac-cluster/backup00.ocr
 
rac2    2014/03/21 16:16:32    /u01/app/11.2.0/grid/cdata/rac-cluster/backup01.ocr
 
rac2    2014/03/21 12:16:31    /u01/app/11.2.0/grid/cdata/rac-cluster/backup02.ocr
 
rac2    2014/03/25 12:04:28    /u01/app/11.2.0/grid/cdata/rac-cluster/day.ocr
 
rac2    2014/03/19 14:26:16    /u01/app/11.2.0/grid/cdata/rac-cluster/week.ocr

可以进行手工备份：
 [root@rac1 bin]# ./ocrconfig -local -manualbackup
 rac1    2014/03/25 14:33:39    /u01/app/11.2.0/grid/cdata/rac1/backup_20140325_143339.olr
 
rac1    2014/03/25 10:34:33    /u01/app/11.2.0/grid/cdata/rac1/backup_20140325_103433.olr
