sles10 sp2, lvm issue

hello

i have created 2 disks on storage and disks are visible from os (sles 10 sp2 x86_64)

2 VG are created and one LV on each VG, filesystems are created and mounted. Files are
created to be sure is filesystem correct.
After reboot filesystems are switched but alllook normal (VG and LV)
