I had a VG scsi_vg consisting of 4 PV's (sda1, sdb1, hdb1,hdc1). 
Now /dev/sdb1 failed and was no longer recogniced by th SCSI-
controller. I had to remove it.

vgscan now fails with the following error:

vgscan -- ERROR "vg_read_with_pv_and_lv(): current PV" can't get data 
of volume group "scsi_vg" from physical volume(s)
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your 
volume group
 
vgchange -ay gives
-- no volume group found

The remaining PV's seem to be ok and the failed disk was only 4Gb 
large.

Here is the output of pvdisplay:

What can I do? How can I remove the no longer existing PV sdb1 from 
scsi_vg?

Any help will be appreciated.
