[root@node1 crs]# ocrconfig -restore /u01/app/crs_home/bin/a.ocr
PROT-22: Storage too small
[root@node1 crs]# ocrconfig -restore /u01/app/crs_home/cdata/crs/backup00.ocr
PROT-19: Cannot proceed while clusterware is running. Shutdown clusterware first
说明：export导出的文件只能是由import导入，restore时，cluster也必须全部离线
具体的操作过程这里不再演示，
10g下怎么增加或者删除ocr磁盘？
在10g中，如果在安装cluster时，如果选择external redundancy那么ocr只能选择一个磁盘，但是通过命令行我们依然可以添加新的磁盘到ocr。如果我们需要替换现有的ocr磁盘，那么必须同时存在两份ocr磁盘才可以，即primary ocr和mirror ocr同时存在时，才可以替换primary ocr或者mirror ocr。
操作实例：
[root@node1 bin]# ocrcheck
