After a yum update, I lost my server.

The problem was that the used disk for booting up was not the proper one I have 3 disks and one of them is the one that is used for booting up the system.

After having recovered my server, my raid was lost (certainly because I tired to rebuild my grub to recover my srv). However I still see the raid that was created before. How can I recover my raid... if possible?
