Ingres has the capability to guarantee integrity of all committed
database transactions in the event of a system software failure or
single storage device failure.  IMPORTANT NOTE: if a second storage
device fails before recovery from an initial failure has taken place,
committed transactions may be lost. 

If you intend to take advantage of this capability, you need to
have at least two independent storage devices available (one in
addition to the one Ingres is being installed on).  If you do not
have two independent storage devices available, but would like to take
advantage of this capability, you should not complete this setup
procedure at this time.
