Recovery using OCR physical backup:

Use physical backups of OCR files to restore OCR files to disk groups:

First, find out which host the backup is on, assuming node1.

/u01/app/11.2.0/grid/bin/ocrconfig -showbackup manual

Stop crs on all nodes

/u01/app/11.2.0/grid/bin/crsctl stop crs

Start asm on node1:

/u01/app/11.2.0/grid/bin/crsctl start crs -excl -nocrs

Check if crs resource is running, it should not be running

CRS-2613: Could not find resource 'ora.crsd', only crsctl status res ora.crsd -init

/u01/app/11.2.0/grid/bin/crsctl status res ora.crsd

CRS-4535: Cannot communicate with Cluster Ready Services

CRS-4000: Command Status failed, or completed with errors.

3. Restore ocr files to disk group:

[root@node1 ~]# /u01/app/11.2.0/grid/bin/ocrconfig -restore /u01/backup_20141118_020104.ocr

If logical backup recovery is used:

/u01/app/11.2.0/grid/bin/ocrconfig -import /u01/ocr.dmp

4. Check the ocr file:

[root@node1 ~]# /u01/app/11.2.0/grid/bin/ocrcheck

Stop crs on node1:

/u01/app/11.2.0/grid/bin/crsctl stop crs -f

Start crs on node1 and node2:

/u01/app/11.2.0/grid/bin/crsctl start crs

7. Perform cluvfy check crs on node1:

cluvfy comp ocr -n all -verbose
