Startup force is a shorthand method of issuing:
shutdown abort
startup
(per

)
When you are implementing VCS, you are indicating that you want uptime. You
don't want an interminable wait while Oracle tidies stuff up. You want it to
come down immediately on the current server, and then be available as
quickly as possible on the other server. This will allow the other
applications that rely on Oracle to become available again in the shortest
possible time.
As far as shutdown abort, this issue has been discussed many times on
this list and the answer has always been that it is safe in the current
versions of Oracle. Yes, a novice DBA should not use it before doing a cold
backup (you need to do a startup followed by a more normal shutdown), but
that is not the situation with VCS switching Oracle to another server in
your cluster.
