Raid 10 loss

Ex 4100 was running on 4 Disk in Raid 10. Got an Issue on Disk 2 that was gone away later. Ex 4100 got Selfupdating on latest Update. But know I have the Problem that no Raid is Configurated an the System whants me to Formate all 4 Disks to generate Raid 10. How can i set up Raid 10 without deleting the Disks?
