You can use this for Windows platforms as well:
%ORACLE_HOME%\bin\ocopy.exe \\.\votedsk# %FILES_LOC%\votedisk1_%HOST%_%YYYYMMDD%%HHSS%.bak >> %IND_LOG%\%HOST%_vd_backup_%YYYYMMDD%.log

ReplyHi Brijesh Dubey,
Thanks for your great explanation on RAC voting disk.
I think there might a very little typo in your post:
“Run the following command as the root user to add a voting disk:
crsctl add css path”
I think it should be:
“crsctl add css votedisk “.
Best Regards,
Bill
Hello Brijesh,
Do we need to bring down cluster services while taking backup of voting disk and ocr files.
Thanks

Hi! Ram
For voting disk backup, you no need to bring down the node. You can take hot backup of votedisk using dd command.
Old backup of voting disk will work fine,until you are not going to make any changes in RAC architecture.
For OCR , you have to shutdown clusterware services before taking external backup using “export ” command, otherwise you can take copy of OCR file, which is created automatically.
To know more about OCR backup, you can refer another article:

Hello Brijesh,
Great article. I’m just wondering why the use of dd? If the files are on OCFS2 is dd still required?
thanks
Sam
cp is sufficient on OCFS2 to backup your voting disk as well as OCR file
ReplyHi Brijesh,
Thanks for the post and good explanantion.
I have a couple of doubts that were sitting in my mind for a long time.
1.What happens if I lost OCR or Voting disk when my cluster is running?
2.Does the entire cluster need to be down to restore the OCR and Voting disk?
Thanks,
Suresh
