[SunRay-Users] Sessions clustering on one server in failover group

[Marcus Young]

Thank you Brad, 
 
yes, the output utgstatus  was normal - utadm -n did the trick (although utadm -l showed lan connections on).  So it looks like the servers were configured not to 'accept' connections.  Although the strange thing was that servers 1 & 3 were running a number of sessions - just not load balanced. 
 
thank you for the advice...

Let's start with the output of /opt/SUNWut/sbin/utgstatus 

 

The results of this command from each FOG server is an important first step. 

 

This should tell us if SRSS thinks it's properly communicating to the other members of the fail over group.

A question about unexpected behaviour with a failover group...   
   
We have been running a Sol10/Sparc 3.1 LDAP auth failover group of 3 servers since mid 2006.  Several weeks ago we replaced the three servers with a similarly configured cluster upgraded to the current patch level.  The data store was migrated from the original cluster to the new cluster.  The group has now been running some time and we are seeing the majority of sessions (active and pseudo) landing on one of the servers (master).  The ratio of sessions is approximately (100:2:20).  In fact the middle server now has no sessions (after a restart).  This is quite different from the behaviour we have seen previously where the sessions balance reasonably well.  Nothing obvious in the SunRay or systems logs.  Would anybody be able to suggest a possible cause and consequent solution?
