Replicating the contents the Sun Ray Data Store has nothing to do with the establishment of a new Sun Ray host group. There's a page in the sunray-users wiki (http://wiki.sun-rays.org/index.php/Host_Group) that talks about this. The group will not form until and unless the servers can see each others' group membership announcements and can agree that their group signatures match. Start by verifying that the group signature on the new machine matches the signature on the existing systems. The output of 'sum /etc/opt/SUNWut/gmSignature' will tell you whether they match. If the signatures match then you need to figure out why group announcements aren't being seen. Group membership traffic is sent as UDP to and from port 7009. Use 'wireshark' or 'snoop' to check that the new server is sending announcements (it should send one every 20 seconds or so) and then try to figure out why those announcements aren't being seen or accepted by the original servers. Announcements are sent as multicast by default, with a time-to-live (maximum subnet hop count) of 1 which means that they won't propagate beyond the directly-attached subnet. If the original machines don't share a subnet with the new one then technically your configuration is unsupported but you might be able to make it work by increasing the TTL on all of the servers. If the original servers have been reconfigured to use a non-default multicast group address or to use broadcasts then you'll need to reconfigure the new server to match, otherwise they'll just talk past each other. When everything is working the 'utgstatus' command should show all three servers. The web GUI basically shows a fancy presentation of the 'utgstatus' output, so until 'utgstatus' is happy the web GUI won't be happy either. OttoM. __ ottomeister Disclaimer: These are my opinions.
