how to restore OCR after complete loss of single OCR diskgroup

crs daemon was not able to start as my ocr diskgroup was not mounted. I logged in to asm instance.

But i was able to mount my other diskgroups

also checked using asmcmd lsdg –discovery command

came to know after checking alertlog CRS diskgroup had corrupted block.


referring doc id 1062983.1 i was able to restore ocr to a new disk with same diskgroup name

please feel free to ask me at
