If I recall ,just install and one-machine AFS cell, run vos syncserv or
vos syncvlb (I can't remember which). Then the volumes will be online.
If you need to recover from tape into non-afs space, look into the
read_tape command. If you want to restore volume dumps from files into
non-afs space, use restorevol.
