Migrate OCR & vote from external to normal or High redundancy in ASM

How to Move OCR & Vote from external to Normal or high.

1) Create New diskgroup(CRS) with suitable redundancy for OCR and Voting files.

2) Ensure that the new diskgroup is mounted on all cluster nodes.

SQL> select name, state, type from v$asm_diskgroup;

NAME                           STATE       TYPE

------------------------------ ----------- ------

CRS                            MOUNTED     EXTERN

OCRVOTE                        MOUNTED     HIGH

REDO                           MOUNTED     EXTERN

CTRL                           MOUNTED     EXTERN

7 rows selected.

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

[root@stg-odb-01 ~]# . grid.env

[root@stg-odb-01 ~]# echo $ORACLE_HOME/

/u01/app/19c/grid/

[root@stg-odb-01 ~]# crsctl query css votedisk

##  STATE    File Universal Id                File Name Disk group

--  -----    -----------------                --------- ---------

 1. ONLINE   5514c6244e044f18bffd1d6339668864 (/dev/oracleasm/disks/OCR3) [CRS]

[root@stg-odb-01 ~]# $ORACLE_HOME/bin/ocrconfig -add +OCRVOTE

[root@stg-odb-01 ~]# $ORACLE_HOME/bin/ocrconfig -delete +CRS

[root@stg-odb-01 ~]# $ORACLE_HOME/bin/crsctl replace votedisk +OCRVOTE

Successful addition of voting disk 05b11d58ce5f4facbfb4ca63ab85a61c.

Successful addition of voting disk 4dcd2003d16a4f31bf593978387af8d0.

Successful addition of voting disk 943b16d7e1b74f54bfc432362509f5d0.

Successful addition of voting disk e9706bb9dd0b4f5cbf80181bcddbae24.

Successful addition of voting disk ff808ea40b124f65bff7ca4cec6eeb56.

Successful deletion of voting disk 5514c6244e044f18bffd1d6339668864.

Successfully replaced voting disk group with +OCRVOTE.

CRS-4266: Voting file(s) successfully replaced

[root@stg-odb-01 ~]#

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

Login as SYSASM using SQLPLUS into ASM instance on one node and run below commands:

SQL> create pfile='/tmp/initnew.ora' from spfile;

SQL> create spfile='+OCRVOTE' from pfile='/tmp/initnew.ora';

That can be verified by below command :  (As grid user or root) 

Now GPNPTOOL will get updated with new ASM SPFILE location.

$ORACLE_HOME/bin/gpnptool get

5) Restart CRS in all nodes to startup CRS using new SPFILE from <CRS> diskgroup 

$> crsctl stop crs

$> crsctl start crs
