To migrate OCR to Oracle ASM using OCRCONFIG

• Ensure the upgrade to Oracle Clusterware 11g release 2 (11.2) is complete. Run the following command to verify the current running version: 
• $ crsctl query crs activeversion 

• Use the Oracle ASM Configuration Assistant (ASMCA) to configure and start Oracle ASM on all nodes in the cluster. 

• To add OCR to an Oracle ASM disk group, ensure that the Oracle Clusterware stack is running and run the following command as root: 
• Before that shutdown the database and also see the rdbms and other compatibity attributes through asmca

        # ocrconfig -add +new_disk_group

• You can run this command more than once if you add multiple OCR locations. You can have up to five OCR locations. However, each successive run must point to a different disk group.

• To remove storage configurations no longer in use, run the following command as root:

    # ocrconfig -delete old_storage_location
    Run the above command for every configured OCR.

The following example shows how to migrate two OCRs to Oracle ASM using OCRCONFIG.

# ocrconfig -add +new_disk_group

# ocrconfig -delete /dev/raw/raw2

# ocrconfig -delete /dev/raw/raw1
