You can activate what's left of the volume group with:

vgchange --partial -ay <VolGroup>

You can remove the missing PV from the VG with:

vgreduce --removemissing <VolGroup>

Note that this will also remove any logical volumes that were using the
missing physical volume. You can run it with --test first to see what
effect it will have.
