How to move OCR , vote file and ASM SPILE to new Diskgroup

There are around 7 steps to move OCR, vote and ASM SPFILE file from one ASM disk group to another ASM disk group.

Below are the steps:

1. Create New diskgroups(CRS) for OCR and Voting files.

   --Login as SYSASM using SQLPLUS into ASM instance on one node and run below command:
   SQL> create diskgroup CRS normal redundancy disk 'RACDB:DISK1' ,'RACDB:DISK2' ,'RACDB:DISK3'
     attribute 'compatible.rdbms'='19.3.0.0', 'compatible.asm'='19.3.0.0';
    Diskgroup created.

2. Mount disk group in all RAC nodes

   SQL> alter diskgroup CRS mount;
     SQL> select name, state, type from v$asm_diskgroup;

3. Move OCR and Vote file from <Current diskgroup>  to <CRS>

   $ORACLE_HOME/bin/bin/ocrconfig -add +CRS
   $ORACLE_HOME/bin/bin/ocrconfig -delete +DATA
   $ORACLE_HOME/bin/crsctl replace votedisk +CRS

4. Change ASM SPFILE location from <Current diskgroup> to <CRS> Diskgroup.

   create pfile='/export/home/grid/pfilen.ora' from spfile;
    create spfile='+CRS' from pfile='/export/home/grid/pfilen.ora';

5. Restart CRS

   --Mount disk group in all RAC nodes:
   SQL> alter diskgroup CRS mount; …. To be sure
   --Restart CRS in all nodes to startup CRS using new SPFILE from +CRS :
   $> crsctl stop crs
   $> crsctl start crs

6. Ensure ALL Cluster resources are started successfully

   $ORACLE_HOME/bin/crsctl stat res -init -t
   $ORACLE_HOME/bin/crsctl check cluster -all
   $ORACLE_HOME/bin/crsctl stat res -t

7. Modify the backup location for the OCR

   ocrconfig -backuploc <new location>
