Migrating OCR, Voting Disk and MGMTDB to another ASM DiskGroup in 12c RAC

Sometime DBA need to move or migrate below mentioned files or DB to different ASM DiskGroup for difference reason. I will show how to move or migrate below mentioned files or DB from one ASM DiskGroup to Another:

  • How to move or migrate OCR and Voting Disk from one ASM Diskgroup to another.
  • How to move or migrate SPFILE and PWDFILE from one ASM Diskgroup to another.
  • How to move or migrate MGMTDB from one ASM Diskgroup to another.

How to move or migrate OCR and Voting Disk from one ASM Diskgroup (+OCR) to another (+OCR_VOTE):

Create New ASM DiskGroup:

SQL> CREATE DISKGROUP OCR_VOTE NORMAL REDUNDANCY
FAILGROUP controller01 DISK 'ORCL:VOTINGDISK01'
FAILGROUP controller02 DISK 'ORCL:VOTINGDISK02'
FAILGROUP controller03 DISK 'ORCL:VOTINGDISK03'
ATTRIBUTE
'au_size'='1M',
'compatible.asm' = '12.1';  

Diskgroup created.
[grid@ocmnode2 ~]$ srvctl status diskgroup -g OCR_VOTE
Disk Group OCR_VOTE is running on ocmnode2

Verifying OCR integrity

Checking OCR integrity...

Checking the absence of a non-clustered configuration...
All nodes free of non-clustered, local-only configurations


Checking daemon liveness...
Liveness check passed for "CRS daemon"

Checking OCR config file "/etc/oracle/ocr.loc"...

OCR config file "/etc/oracle/ocr.loc" check successful


Disk group for ocr location "+OCR_VOTE/ocmnode-cluster/OCRFILE/registry.255.1047949319" is available on all the nodes


Checking OCR backup location "/u01/app/12.1.0/grid/cdata/ocmnode-cluster"

OCR backup location "/u01/app/12.1.0/grid/cdata/ocmnode-cluster" check passed

NOTE:
This check does not verify the integrity of the OCR contents. Execute 'ocrcheck' as a privileged user to verify the contents of OCR.

OCR integrity check passed

Verification of OCR integrity was successful.
