Moving Oracle Clusterware Files from NFS to Oracle ASM

You can move Oracle Cluster Registry (OCR) and voting files from Network File System (NFS) to Oracle Automatic Storage Management (Oracle ASM) disk groups.

As Oracle Grid Infrastructure installation owner (grid), create the Oracle ASM disk group using ASMCA.
```
./asmca
```
Follow the steps in the ASMCA wizard to create the Oracle ASM disk group, for example, DATA.

As grid user, move the voting files to the Oracle ASM disk group you created:

crsctl replace votedisk +DATA

The output of this command is as follows:

CRS-4256: Updating the profile
Successful addition of voting disk 24c6d682874a4f1ebf54f5ab0098b9e4.
Successful deletion of voting disk 1b5044fa39684f86bfbe681f388e55fb.
Successfully replaced voting disk group with +DATA_DG_OCR_VDSK.
CRS-4256: Updating the profile
CRS-4266: Voting file(s) successfully replaced

As grid user, check the Oracle Cluster Registry (OCR) status:

./ocrcheck

The output of the command is as follows:

Status of Oracle Cluster Registry is as follows :
         Version                  :          4
         Total space (kbytes)     :     409568
         Used space (kbytes)      :       1380
         Available space (kbytes) :     408188
         ID                       :  288871063
         Device/File Name         : /oradbocfs/storage/12101/ocr
         Device/File integrity check succeeded
         Cluster registry integrity check succeeded

As root user, move the OCR files to the Oracle ASM disk group you created:
```
./ocrconfig -add +DATA 
```
As root user, delete the Oracle Clusterware files from the NFS location:
```
./ocrconfig -delete ocr_file_ path_previously_on_nfs
```
