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.
