Adi,

Your question seems slightly confused. If you want to implement a 
fail-over Apache service you need one two node cluster, not two single 
node clusters. Separate clusters are only relevant to disaster recovery 
systems, usually using a 2 node cluster and a single node cluster with 
the addition of the Sun Cluster Geographic Edition software.

A quorum device, usually a disk, allows the remaining cluster node to 
stay up when it loses contact with the other cluster node.

Please read the Solaris Cluster manuals for more info. In particular the 
concepts guide and then the Apache Data Service guide.

Hope that helps,

Tim
