Re: Further adventures in the world of RAC - Part 1

Yes. Doing a dd on the OCR destroys the CRS installation. However most of the times, we just re-install the CRS than debugging what went wrong as re-install is faster than looing the pile of trace files. So just wipe out the CRS install, DD the OCR,voting and ASM disks, include the verify the ASMLIB and see the disks are seen in both the location (as per my earlier mail), include the modified ASM_DISKSTRING parameter in the ASM init.ora file and you are good to go.

You have to re-initialize cluster registry device by doing dd if=/dev/zero of=<cluster registry> bs=1024k count=64
