Can you reinstall the  OS and leave /vicepa and /vicepb alone during the
install? Then once you are back in business install openafs , mount
/vicpea /vicepb and away you go?
We do this often however our partitions are on attached jbods so we swap
out servers or rebuild the server from an install server but its
basically the same thing. It works as long as the the server hostname
remains the same.
