RE: Expand a virtual drive on a Dell Perc 6/i Raid 6?
You were doing it right the first time (i.e. replace one drive at a time, let it rebuild, then repeat for the rest of the drives), the previous poster probably meant 'rebuild' and not 'reconfigure'. Why did you stop the reconfigure after replacing all 5 drives? Or if you didn't stop it, what was the outcome (it should have worked...)
Don't delete your raid array, that's clearly not the correct method!
