Here are some additional tasks that you may need to perform for failover group administration.

6.8.1 How to Take a Server Offline and Online

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
    

6.8.2 How to Disable Load Balancing

In the auth.props file, set enableLoadBalancing to false.

6.8.3 How to Show the Current Sun Ray Data Store Replication Configuration

# /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).

6.8.4 How to Remove the Replication Configuration

# /opt/SUNWut/sbin/utreplica -u

6.8.5 How to View the Failover Group Status

Note

Sun Ray server broadcasts do not traverse routers or servers other than Sun Ray servers.

Command-Line Steps

  • View the failover group status for the local Sun Ray server:

    # /opt/SUNWut/sbin/utgstatus
    

Admin GUI Steps

  1. Click the Servers tab.

    The Mode column lists the status for all the servers in the failover group.

  2. Select a server name to display its Server Details screen.

  3. 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.
