I'm fairly sure that Intel Matrix metadata cant be created/modified by fbsd, only read. You should be able to do whatever rebuild operations you need in the BIOS I believe, but that would be an offline operation, clearly. I may be mistaken, and the driver can handle array rebuilds for matrix. If it can, the command you are looking for is 'atacontrol rebuild ar0', see atacontrol(8).
