Remove volume group it's lvs and filesystems after vg's pv was deleted ?

Hi,

Physical volume of vg was removed permanently by acident. What I need right now is to remove all vg's objects(vg itself, vg's lvs, vg's filesystems) to prepare to add new pv and create new volume group and it's objects.
This is from reducevg manual:
"Sometimes a disk is removed from the system without first running reducevg VolumeGroup PhysicalVolume. The VGDA still has this removed disk in it's memory, but the PhysicalVolume name no longer exists or has been reassigned. To remove references to this missing disk you can still use reducevg, but with the Physical Volume ID (PVID) instead of the disk name: reducevg VolumeGroup PVID"

I executed the following:
-bash-2.05b# reducevg vglgpaps 000304cb68e16728
0516-010 lqueryvg: Volume group must be varied on; use varyonvg command.
0516-882 reducevg: Unable to reduce volume group.
-bash-2.05b#

How can I do varyonvg if there is no pv ?
Acording to manual it should work - but it doesn't !
What am I donig wrong ?
(maybe I should remove vg's lvs and filesystems before - but how ?)

thank you in advance
Vilius

NAME
vgremove - remove LVM volume group definition from the system SYNOPSIS
vg_name ... Remarks If a combination of volume groups version 1.0 and 2.0 or higher arguments are supplied, then the arguments might not be processed in the order they are listed on the command line. DESCRIPTION
The command removes from the system the last physical volume of the volume group and the definition of the volume group or groups specified by vg_name .... Since all system knowledge of the volume group and its contents are removed, the volume group can no longer be accessed. To move a volume group from one system to another, use the command instead (see vgexport(1M)). Before executing remove all logical volumes residing on the last physical volume by executing (see lvremove(1M)). Before removing a volume group, two steps are necessary: 1. Remove all the logical volumes belonging to the group by using the command (see lvremove(1M)). 2. Remove all but one physical volume belonging to the volume group by using the command (see vgreduce(1M)). If there is any physical volume group created under vg_name ..., the physical volume group information is also removed from file Options and Arguments recognizes the following option and argument: For each volume group removed, also remove its volume group directory and file vg_name The path name of a volume group. EXTERNAL INFLUENCES
