First check the OCR disk.

[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.

Back up the asm parameter file

[grid@rac1grid] $sqlplus / as sysasm

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

Backup OCR disk

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

Simulate the destruction of the OCR disk:

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

After the destruction, check the cluster status.

[grid@rac1grid] $crsctl check crs

CRS-4638: Oracle HighAvailability Services is online

CRS-4537: Cluster ReadyServices is online

CRS-4529: ClusterSynchronization Services is online
