You already have the grub configured on sda (original primary boot device) or you can't boot. The ideea is to configure grub on sdb - or the secondary hdd - after you create the raid matrix and before anything bad happens so if the Fail event happens on the sda (original primary boot device) you will boot for sure with the sdb (original secondary boot device) moved in place of sda.
