Let's start with the obvious: Can you post your disk layout?  Mirrored how?  Gmirror/ZFS/Hardware raid/etc?  MBR or Gpart?

What commands have you tried thusfar?

What does the boot so far look like (i.e. are you hitting the stage 0 boot loader, and getting the loader prompt?)

More info required, please, but this sounds very fixable.
