Dear Erman,

We have a diskgroup OCRVOTE with high redundancy with 5 disks in it(voting disks,ocr,spfile)

[oraprod@nodedb1~]$ crsctl query css votedisk
##  STATE    File Universal Id                File Name Disk group

 5. ONLINE   c7f6893759c14fc2bf01b347d38e9fdb (ORCL:OCRVOTEDISK5) [OCRVOTE]
Located 5 voting disk(s).

I agree for high redundancy diskgroup,we will have 3 OCR copies.

If any of the OCR copy is corrupted,will oracle take care of it by reading other copies and writing to the corrupted one?
OR
Do we need to take any manual action

Thank you
