To set up a high availability configuration, you create two nodes, each of which defines the other’s NetScaler Gateway IP address as a remote node. You can start by logging on to one of the two NetScaler appliances that you want to configure for high availability and add a node. Specify the other appliance’s NetScaler Gateway IP address as the address of the new node. Then, log on to the other appliance and add a node that has the NetScaler Gateway IP address of the first appliance. An algorithm determines which node becomes primary and which becomes secondary.
Before you configure the appliances, add a high availability node. This node represents either the first or second NetScaler Gateway in the high availability pair. To configure high availability, you first create the node and then you configure the high availability settings.
