Synchronizing Citrix Gateway appliances

Automatic synchronization of Citrix Gateway appliances in a high availability pair is enabled by default. With automatic synchronization, you can make changes to one appliance and enable the changes to propagate automatically to the second appliance. Synchronization uses port 3010.

Synchronization starts when the following occurs:

  • The secondary node restarts.
  • The primary node becomes secondary after a failover.

You can disable synchronization, which prevents the secondary Citrix Gateway from synchronizing its configuration with the primary Citrix Gateway when a change occurs on the primary appliance. You can also force synchronization.

You enable or disable high availability synchronization on the secondary node in the pair.

To enable or disable high availability synchronization

  1. In the configuration utility, on the Configuration tab, in the navigation pane, expand System and then click High Availability.
  2. In the details pane, on the Nodes tab, select a node and then click Edit.
  3. In the Configure Node dialog box, under HA Synchronization, do one of the following:
    • To disable synchronization, clear the Secondary node will fetch the configuration from Primary check box.
    • To enable synchronization, select the Secondary node will fetch the configuration from Primary check box.
  4. Click OK. A message appears in the status bar stating that the node configuration is successful.

To force synchronization between appliances

In addition to automatic synchronization, Citrix Gateway supports forced synchronization between the two nodes in a high availability pair.

You can force synchronization on both the primary and secondary Citrix Gateway appliances. However, if synchronization is already in progress, the command fails and Citrix Gateway displays a warning. Forced synchronization also fails in the following circumstances:

  • You force synchronization on a standalone system.
  • The secondary node is disabled.
  • You disable high availability synchronization on the secondary node.
  1. In the configuration utility, on the Configuration tab, in the navigation pane, expand System and then click High Availability.
  2. On the Nodes tab, click Force Synchronization.
