RAC: change the voting disk and ocr location

• Change VOTE and OCR location

First we have to create new ASMLib binding

[root@lodzio ~]# oracleasm createdisk asmgrid /dev/sdc1 
Writing disk header: done
Instantiating disk: done

Then we have to create new ASM diskgroup and set the appropriate attributes (at least ‘compatible.asm’)

[oracle@lodzio ~]$ sqlplus / as sysasm

With the Real Application Clusters and Automatic Storage Management options

SQL> create diskgroup gridasm    
  2  external redundancy disk 'ORCL:ASMGRID';

Diskgroup created.

SQL> ed
Wrote file afiedt.buf

  1  alter diskgroup GRIDASM
  2* set attribute 'compatible.asm'='11.2.0.0.0'
SQL> /

Diskgroup altered.

SQL> 2

SQL> c /asm/rdbms
  2* set attribute 'compatible.rdbms'='11.2.0.0.0'
SQL> /

Diskgroup altered.

Then we can add a new location for OCR.

[root@lodzio ~]# ocrconfig -add +GRIDASM
[root@lodzio ~]# ocrcheck
Status of Oracle Cluster Registry is as follows :
	 Version                  :          3

                                    Device/File not configured

	 Cluster registry integrity check succeeded

	 Logical corruption check succeeded

And remove the old location

[root@lodzio ~]# ocrconfig -delete +GRID
[root@lodzio ~]# ocrcheck

                                    Device/File not configured

	 Cluster registry integrity check succeeded

	 Logical corruption check succeeded

Now we can replace the voting disk location

[root@lodzio ~]# crsctl replace votedisk +GRIDASM
Successful addition of voting disk 4c509ae74cb14f4ebf10f856b3dd7f7a.
Successful deletion of voting disk 28302806fe694f6bbfc9de3ff3be0b46.
Successfully replaced voting disk group with +GRIDASM.

[root@lodzio ~]# crsctl query css votedisk
