some more informations:

- the system didn't crash but was switched of before "vgchange -a n" was
called
- pvdisplay shows "PV Status available" for all PV's

- vgcfgrestore
  even some backups back doesn't help
- vgcfgrestore -t -ll -f /etc/lvmconf/DATAVG.conf -n DATAVG
  showns the same results as pvdisplay
- pvdisplay on all 3 partions shown "good" results

- pvdata -a /dev/hdb1 /dev/hdc1 /dev/hdd1
  looks good 
  displays the same "VG UUID" for all PV's

- tried vgimport -f -v DATAVG /dev/hdb1 /dev/hdc1 /dev/hdd1
