Sun Cluster question

Hello everyone
I've inherited an Oracle Solaris system holding ASE Sybase databases. The system consists of two nodes inside a Sun Cluster. Each of the nodes is hosting 2 Sybase database instances, where one of the nodes is active and other is standing by. The scenario at hand is that when any of the databases on one node fails for whatever reason, the whole system gets shifted to the second node to keep the environment going. That works fine.
My intended scenario:
Each node is holding 2 database instances, both nodes ARE working at the same time so that each one is serving one instance of the database. In the event of failure on one node, the other one should assume the role of BOTH database instances till the first one gets fixed.
The question is: is that possible? and if it is, does that require breaking the whole cluster and rebuilding it? or can this be done online without bringing down the system?
Thanks a lot in advance

NAME

       clprivnet - SUNW,clprivnet Sun Cluster private network driver

SYNOPSIS

       /dev/clprivnet

DESCRIPTION

       Note -

	 Beginning  with  the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software
	 still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more  infor-
	 mation about the object-oriented command set, see the Intro(1CL) man page.

       The  SUNW,clprivnet  Sun  Cluster  private  network driver is a STREAMS pseudo driver supporting Sun Cluster resident applications that use
       standard Solaris interfaces to communicate over the Sun Cluster private network. By striping data traffic over all links, this driver opti-
       mally utilizes the bandwidth of the private network while supporting highly available, software fault-tolerant communication.

APPLICATION PROGRAMMING INTERFACE

       The driver is supported by the character-special device /dev/clprivnet, but is reserved for Sun Cluster internal operation and the standard
       Solaris network utilities. This interface must not be directly used for general application communication.

ADMINISTRATION

       The administration and configuration of the driver as a network interface is done completely by the Sun Cluster infrastructure internals.

FILES

       /dev/clprivnet

	   clprivnet special character device

       /usr/kernel/drv/clprivnet.conf

	   System-wide default device driver properties
