Let's say raid-controller died and I want to replace it while preserving old raid-arrays. What is proper way to do it?
Obviously, I get the same controller with the same firmware version (which I keep in reserve for exactly this case). Then I remove the old controller, insert the new one, and attach cables to the same ports as on the old controller. What to do now? Simply boot-up, expecting everything works? I doubt it's that simple. Or do I have to go to controller-bios and re-construct arrays? How can I do it without loosing data?
