2. 2 nodes stop the cluster and modify the configuration file (change the name of the disk group inside to the new disk group)

. / crsctl stop crs

Vi / etc/oracle/ocr.loc

3. Start a node to exclusive mode and confirm whether the disk group + NEW is mount. If not, manually mount.

Crsctl start crs-excl-nocrs

SQL > select GROUP_NUMBER, NAME,STATE from v$asm_diskgroup

GROUP_NUMBER NAME STATE

1 ASM_DATA1 MOUNTED

2 ASM_FL MOUNTED

3 CRS MOUNTED

4 DATA MOUNTED

4. Use OCR backup to restore OCR to a new disk group (be careful to change ocr.loc ahead of time)

#. / ocrconfig-restore / u01/11.2.0/grid/cdata/rac-cluster/backup_20170801_023201.ocr
