- The easiest way is to dust off one of those Microvax IIs and boot it into
- the cluster as a satellite, and give it a vote. You don't have to do anything
- with it except let it be a tiebreaker. As long as one of the 3100/80s and
- the Microvax II is up, the cluster remains running with a 3100/80 available.
-
- You may be able to do something with interconnecting the SCSI bus and having
- a quorum disk but I know nothing about that, even if it's possible.
