This isn't exactly a Centos question but maybe someone here can help: Does the AACRAID controller (as in an IBM 3550) store its config info on the drives or internally? I only have one of the boxes and want to load Centos 3.x on several drives which can be swapped into servers at another location. With SCSI, all that took was a full disk dd copy and a little fiddling with the HWADDR for the nics. However these don't even see a disk until you run the raid setup in bios.
Does anyone know if a new server will recognize the setup (one drive, no raid) from the cloned disk or what it will take to make it accept the swap?

We don't have that exact box, but we've got racks full of ibms like it. It stores the information on both the controller and the drives. If they don't match, you'll get a warning that tells you they don't match and you can either drive on with the existing config, or you can choose to read the configuration from the drive. If you're swapping more than one disk, they have to be kept in the same order, or else it'll get amazingly irritable, and you can kiss your data goodbye.

Thanks - It's just one disk but I need to know what the person installing it has to do. Maybe I'll see it when I swap in my first cloned disk to test booting from it. I suppose I should be PXE-booting a common image instead of using local disks anyway...
