From Scott's post it seemed to say the data written to the drives that allows rebuilding the array when the RAID is replaced is what is missing. If that data is gone, aren't you hosed? Unless it is backed up somewhere?

It's not the disks that are bad, it's the controller itself. It's ROM is messed up.

With luck the flashed controller will pull the array data back in.

Thanks again to everyone who replied and gave feedback on this. It's great to know that there's a solid community of knowledgeable people who are willing to share their expertise - I really appreciate it!!

Sadly we didn't find your solution. But happily you found it on your own!

So HP engineering said that this should work but they had not tested it. Make sure you are fully up to date on the firmware and the P410 should be able to go to the P400 safely. But.... caveat emptor, of course.
