Chapter 1. Red Hat Cluster Suite Overview
Figure 1.32. The REDUNDANCY Panel
Redundant server public IP
The public real IP address for the backup LVS router.
Redundant server private IP
The backup router's private real IP address.
The rest of the panel is for configuring the heartbeat channel, which is used by the backup node
to monitor the primary node for failure.
Heartbeat Interval (seconds)
Sets the number of seconds between heartbeats — the interval that the backup node will
check the functional status of the primary LVS node.
Assume dead after (seconds)
If the primary LVS node does not respond after this number of seconds, then the backup
LVS router node will initiate failover.
Heartbeat runs on port
Sets the port at which the heartbeat communicates with the primary LVS node. The default
is set to 539 if this field is left blank.
10.4. VIRTUAL SERVERS
The VIRTUAL SERVERS panel displays information for each currently defined virtual server.
Each table entry shows the status of the virtual server, the server name, the virtual IP assigned
to the server, the netmask of the virtual IP, the port number to which the service communicates,
the protocol used, and the virtual device interface.
