Restore image on raid1 volume


I have used the urbackup for image backup on various pc which is working very good also restore of the image are working perfect
I have now tried to backup a server which are installed with RAID1(Mirror) and thougth that I was able to restore the image on another server with RAID1 configured.
But I can only restore to one of the disk instead of restore the volume.
Is it the urbackup that are unable to see the Volume or ??
It is Intel Rapid storage that is used for the SATA Raid volume.
Thanks in advance
