Well, this only makes sense if there is LV(s) which don't have *any* PEs
alocated on the crashed disk. If not so you'ld end up in an filesystem mess
(assuming that the LV(s) contain(s) filesystems) anyway, because fs metadata
and data will be missing.

If you still want to go for it you need a replacement drive, vgcfgrestore
the LVM metadata to it and restart LVM.
In order to avoid such problems you might consider to go for soft/hard RAID
as PV storage.
