首先检查下OCR盘

[grid@rac1 cdata]$ ocrcheck

Status of OracleCluster Registry is as follows :

Version : 3

Total space (kbytes) : 262120

Used space (kbytes) : 3068

Available space (kbytes) : 259052

ID : 1088979561

Device/File Name : +CRS

Device/Fileintegrity check succeeded

Device/Filenot configured

Cluster registry integrity checksucceeded

Logical corruption check bypassed dueto non-privileged user

[grid@rac1grid]$ cluvfy comp ocr -n all

Verifying OCR integrity

Checking OCRintegrity...

Checking the absence ofa non-clustered configuration...

All nodes free ofnon-clustered, local-only configurations

ASM Running checkpassed. ASM is running on all specified nodes

Checking OCR configfile "/etc/oracle/ocr.loc"...

OCR config file"/etc/oracle/ocr.loc" check successful

Disk group for ocrlocation "+CRS" available on all the nodes

NOTE:

This check does notverify the integrity of the OCR contents. Execute 'ocrcheck' as a privilegeduser to verify the contents of OCR.

OCR integrity checkpassed

Verification of OCRintegrity was successful.

备份asm参数文件

[grid@rac1grid]$ sqlplus / as sysasm

SQL> createpfile='/tmp/asm_pfile_20150306.txt' from spfile;

备份OCR盘

[root@rac1 grid]#bin/ocrconfig-export /tmp/ocr_bak20150306.dmp

模拟破坏OCR盘：

[root@rac1grid]# dd if=/dev/zero of=/dev/oracleasm/disks/CRS bs=1024 count=1000

破坏完后，检查集群状态

[grid@rac1grid]$ crsctl check crs

CRS-4638: Oracle HighAvailability Services is online

CRS-4537: Cluster ReadyServices is online

CRS-4529: ClusterSynchronization Services is online

CRS-4533: Event Manageris online
