Lost partitions

[skavlak]

Hi,
My problem is after installing W2K3 enterprise with smartstart 7.40 on ML370 server with MSA30 enclosure (contains 7 disks raid5), operating system cannot see the partitions on the raid5 array. There are two smart array 642 controllers on the server. Operating system was installed on raid1 configuration two 36GB disks. Raid5 array contains 7 300GB disks and originally has 4 partitions. Unfortunately, on the installation MSA30 was not detached from the SA642 controller. Can we recover all the partitions before attempt to using backup? Thanks in advance.
