Server Status
The VMS Connection Manager provides the status of the VMS and each of the
servers in a redundancy group. The Connection Manager, when running, will
display its icon in the Windows Task bar at the bottom right of the screen. When
the mouse is positioned over this icon, a status pop-up appears displaying infor-
mation on the VMS and the servers, as shown in figure C-2, below.
Figure C-2 Server Status Pop-Up
There are four possible server states:
• active
• standby
• contention
• disconnected
If no servers are connected, the status message will read “Vipersat Management
System Disconnected”.
The server to which the console is currently connected (the local server) is iden-
tified by whatever was entered in the Connect To dialog; either its assigned
name or its IP address (as appears in the first line of the example shown in
figure C-2). The next server status that is displayed is that of the local server,
followed by any remote servers listed by their IP address.
Installing & Configuring VMS Server Redundancy
Installation of a redundant VMS server configuration in a VMS controlled
network requires the following:
• Two or more dedicated servers and a client workstation.
• The servers and the workstation should be co-located (in the same physical
location) and connected to the same Ethernet LAN.
• A dedicated IP address for each VMS server.
