Being able to take servers offline makes maintenance easier. In an offline state, no new sessions are created. However, old sessions continue to exist and can be reactivated unless the Sun Ray Software is affected.
Take a server offline:
# /opt/SUNWut/sbin/utadm -f
Take a server online:
# /opt/SUNWut/sbin/utadm -n
# /opt/SUNWut/sbin/utreplica -l
The result indicates whether the server is stand-alone, primary (with the secondary host names), or secondary (with the primary host name).
Sun Ray server broadcasts do not traverse routers or servers other than Sun Ray servers.
View the failover group status for the local Sun Ray server:
# /opt/SUNWut/sbin/utgstatus
Click the Servers tab.
Select a server name to display its Server Details screen.
Click View Network Status.
The Network Status screen is displayed.
The Network Status screen provides information on group membership and network connectivity for trusted servers, which are those servers in the same failover group.
