Cluster Configuration
CommandCenter clustering is using two CommandCenter nodes, one Primary node and one Backup node,
for backup security in case of Primary CommandCenter node failure. Both nodes share common data for
active users and active connections, and all status data is replicated between the two nodes.
Devices in a CommandCenter cluster must be aware of the IP of the Primary CommandCenter node in
order to be able to notify the Primary node of status change events. If the Primary node fails, the Backup
node immediately assumes all Primary node functionality. This requires initialization of the
CommandCenter application and user sessions (all existing sessions originating on the Primary
CommandCenter node will terminate). The devices connected to the Primary CommandCenter unit will
recognize that the Primary node is not responding and will respond to requests initiated by the Secondary
node.
To Set Primary CommandCenter Node:
1.
On the
Setup
menu, click
Cluster Configuration.
The
Cluster Configuration
screen appears.
Figure 131 Cluster Configuration Screen
2.
The CommandCenter unit from which you create a cluster is automatically considered the Primary
Node. Type a name for this Primary Node in the
Cluster Name
field near the bottom of the screen.
3.
When finished, click
Create Cluster.
