Or simply change boot priority of the harddisks in the bios? That way you should be able to fully boot the system from both disks.When I set up a system such as this I always test afterward that the system can be booted from each disk individually. Don't boot past grub. Just boot to grub to verify. If you boot past grub into a degraded raid system it will create a "split brain" problem with each disk thinking it is newer and requiring the raid to be rebuilt manually.
