accidentally deleted diskgroup including OCR OCR. What should I do to get the OCR?

OS: Linux redhat 5

DB version is: 11.2.0.3

I was trying to reorg the diskgroup and accidentally deleted the diskgroup that including OCR.

How I can't bring asmca and don't know what to do here.

I tried to restore the backup, it seems the diskgroup deleted original backup.

Please help here.

Thank you.

You can use the following procedure if diskgroup with OCR is lost.

1. start a single node.

2. stop the crs:

crsctl stop crs f

3. start the crs in exclusive mode:

crsctl start crs - Excl.

4. start ASM, asm_diskstring set (if necessary) and create the diskgroup bearing the same name (ASM may begin with the placeholder file)

5. the list of OCR, and OCR to restore the most recent backup backups:

ocrconfig - showbackup

ocrconfig-restore

6. stop the crs:

crsctl stop crs f

7. If the vote of the files are Ok, restart all nodes.

On the OTHER - restore files with right to vote:

crsctl start crs - Excl.

connect to ASM and asm_diskstring set (if necessary)

crsctl replace votedisk +.

crsctl stop crs f

Restart all nodes
