Thanks Shreedhar for you response.

Answers to your questions:
1. yes, we made sure that these two servers are in the same subnet (shoal documentation makes this clear and also one of Sun's blog posts.
Machine 1:
lo0:1: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
qfe0:1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 10.70.7.36 netmask ffffffc0 broadcast 10.70.7.63

Machine 2:
lo0:4: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
e1000g0:4: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 10.70.7.24 netmask ffffffc0 broadcast 10.70.7.63

2. Unfortunately there is no single place to get the documentation on this, so here is a list of documents I used (all from http://docs.sun.com/app/docs/coll/1343.4 - SJSAS 9.1 documentation suite)
- SJSAS9.1 High Availability Administration Guide http://docs.sun.com/app/docs/doc/819-3679
- SJSAS9.1 Quick Start Guide
- SJSAS9.1 Installation Guide
- SJSAS9.1 Administration Guide

The High Availability Admin Guide points to other guides listed above.

This tech ref was very good.
- http://developers.sun.com/appserver/reference/techart/glassfishcluster/


Also this blog post was useful:
http://blogs.sun.com/Prashanth/entry/setting_up_load_balancing_in

I think having simple diagnostic tools to troubleshoot basic multicasting as part of shoal will be beneficial (the JGroups one is very generic, something like that is good for debugging/troubleshooting).
