-- Disable the database so it will not start after restarting CRS:

srvctl disable database -d TEST

-- Restart CRS with root user:

 /oracle/product/11.1.0/crs/bin/crsctl start crs  
 /oracle/product/11.1.0/crs/bin/crsctl stop crs  

-- Take backup of OCR with root user:

 /oracle/product/11.1.0/crs/bin/ocrconfig –manualbackup
You’ll find the backup file under CRS HOME:
ls -alrt /oracle/product/11.1.0/crs/cdata/server1_cluster/

-- Take a backup of voting files with dd command: 

 dd if=/dev/voting1_test11g of=/oracle/product/11.1.0/crs/cdata/server1_cluster/voting1_test_yedek bs=131072 count=4000

-- Replace OCR files with root user:

 /oracle/product/11.1.0/crs/bin/ocrconfig -replace ocr /dev/ocr1_11g
 /oracle/product/11.1.0/crs/bin/ocrconfig -replace ocrmirror /dev/ocr2_11g

-- Replace voting files with root user:

 /oracle/product/11.1.0/crs/bin/crsctl delete css votedisk /dev/voting1_test11g
 /oracle/product/11.1.0/crs/bin/crsctl add css votedisk /dev/voting1_11g

 /oracle/product/11.1.0/crs/bin/crsctl add css votedisk /dev/voting3_11g

If you see the following error after “crsctl delete” command, you can use “-force” option and re-run the command.
