boot once.

vgexport /dev/vgwhatever;
vgimport /dev/vgwhatever <list of drives that didn't croak>

you will now have your VG back on line with whatever portion of the
data is no the clean drives.  any LV's spanning the dead drive are
likely to be lost anyway.  It'll take you less time to vgextend the
imported group onto a new, working drive an recover backups onto
new LV's than almost anything else you can try.
