I've come across a production SQL Server 2008 box that has quite a few databases with PAGE_VERIFY option set to NONE. I'm going to set the PAGE_VERIFY option to CHECKSUM. If I understand correctly, I must rebuild the existing indexes for CHECKSUM to affect them. Also, that if I rebuild a clustered index the non-clustered indexes will be rebuilt as well.
- What will happen to the existing indexes if I can't rebuild them right away?
- Are the existing indexes still usable after setting CHECKSUM without a rebuild?
Thanks!
