Can a NS704 be used as an NS702?

  I inherited a Celerra NS704 system, but it only came with 2 DMs. The system was wiped clean and I need

to re-install Linux and DART. During the install it reports it finds 4 data movers but only 2 show up as expected.

  At this point the install stops and keeps searching for DM 3 and 4.

When the install reports it finds 4 but can only bring 2 online it wants me to search again or continue.

Select yes for 2 DMs and continuing does not install DART. I get the CS login prompt and

the only account available is root.

  So is it possible to fake out the install so it only looks for 2 DMs?
