  SVN rev 215932 on 2010-11-27 03:59:55Z by mjacob
  
  This is an MFC of 205847
  Change how multipath labels are created and managed. This makes it easier
  to support various storage boxes which really aren't active-active.
  
  We only write the label on the *first* provider. For all other providers
  we just "add" the disk. This also allows for an "add" verb.
  
  A usage implication is that you should specificy the currently active
  storage path as the first provider.
  
  Note that this does not add RDAC-like functionality, but better allows for
  autovolumefailover configurations (additional checkins elsewhere will support
  this).
