utreplica sets up SRDS data replication. Its effect is not visible
directly via the web admin GUI.
utconfig runs utgroupsig to set a common group signature in all FOG
members. It's the group signature that defines FOG membership in terms
of failover, load balancing, and session location.
If you're not seeing all your FOG members in the web admin GUI (or in
/opt/SUNWut/sbin/utgstatus) then that indicates that either your group
signatures were not set to a common value (compare the passwords in
/etc/opt/SUNWut/gmSignature, but do not edit those files directly - if
you need to change them use utgroupsig), or you're having network issues
between your servers.
What does utgstatus report? You should see all of your FOG servers, with
a "T" in the first host flag column (indicating that the host is a
Trusted member of the FOG).
Are all of your servers directly connected to each other on a common subnet?
You may be experiencing IP multicast issues with your switches - this is
rather common I'm afraid.
If your servers are directly connected to each other, than you may edit
/etc/opt/SUNWut/auth.props to set enableMulticast=false. This tells SRSS
to use broadcast instead of multicast for the Group Membership protocol.
You will need to run utrestart after this to pick up the change. You'll
need to perform this operation on each server.

All,
We are experiencing a problem with secondary servers not showing up in the
web admin GUI.
Configured web admin for all servers. When logged into primary web admin
and selecting servers tab
only the primary is listed.
Has anyone seen this issue before?
Infrastructure
bash-3.00# ./utadm -l (primaryhost)

Sun Ray interconnect framework is not configured
Primary is v490 running solaris 10 10/08 with srss 4.1 all patches are
current.
Network subnet is 255.255.254.0.
Secondaries are Solaris 10 10/08 x86 running is ESX 3.5 VM with srss 4.1 all
patches are current.
Network subnet is 255.255.254.0.
When FOG was created, we received no errors from the primary or the
secondaries.
This is the utreplica output.
Primary:
bash-3.00# ./utreplica -l
Sun Ray Core Services 4.1
Administration Failover Configuration
primaryhost is a primary server for:
secondary01
secondary02
secondary03
Same output for utreplica for all secondaries.
Secondary:
bash-3.00# ./utreplica -l
Sun Ray Core Services 4.1
Administration Failover Configuration
secondary01 is a secondary server
The primary server is: primaryhost
Thank you.
