Raid LVM problems

Hi all,

I have a problem with my LVM setup, My servers has 5 disks,
1x IDE boot harddisk using EXT3 and 4 sata drives in a software raid config… IDE Boot disk failed, replaced boot disk and re-installed openSuSE 11.0 but cannot get my LVM to detect the PV’s of LV’s.

pvscan

No matching physical volumes found
vgscan
Reading all physical volumes. This may take a while…
No volume groups found

Yast show disks as follows:
/dev/sda 55.9 GB ST360014A
/dev/sda1 125.4 MB Linux native /boot
/dev/sda2 2.0 GB Linux swap swap
/dev/sda3 53.7 GB Linux native /
/dev/sdb 465.7 GB ST3500320AS
/dev/sdb1 465.7 GB Linux RAID

/dev/sdd 465.7 GB ST3500320AS
/dev/sdd1 465.7 GB Linux RAID

Can anybody help or suggest possible ways to get my data back ?

Kindest regards
