Re: Oracle RAC 10.2.0.3 - IBM 5.3 - Cybernetics - Block Corruption

Thanks for the response. Looks like we are going to just hook up a Linux box to Cybernetics (which works) and then expose the disk devices to the AIX box via Linux, so Linux will act as a middle man. We are just trying to certify some software so we don't require a production set up at this point. We are told Solaris and Linux work fine with Cybernetics, the issue as been IBM. Pretty sure the block corruptions are related to the disk issues, the only thing I can't explain is that I have another database running in the same cluster and it hasn't been corrupted yet. But since the issue is random it might just be a coincidence.
