Re: HP-UX 11/9iR2/dbv

(reposting)

Hi!

In 9i, you can actually "dbv" files online. No blocks are falsely detected as corrupt, they're just rescanned in case block header & tail SCN and wrap bytes don't match. If the block is continuously in change, then block is reported as being in flux not corrupt.
