When you want to ensure continuous availability and disaster recovery for your ADC instances, you can configure a GSLB site group. It balances the load across sites by directing client requests to the closest or best performing site, or to surviving sites if there is an outage.

Sometimes, in a GSLB site group, the configuration objects of the ADC instances try to overwrite each other. It leads to a race condition. To address such issues, you need to control the primary node selection in the GSLB site group. The configuration in the primary node will be applied to the remaining ADC instances. In NetScaler Console, you can create a GSLB site group and do the following:

Choose a primary node among the selected ADC instances.
Set the priority order for primary node selection if the selected primary node goes down.

You can view your GSLB site groups in Infrastructure > Instances > GSLB Site Group.

Create a GSLB site group

Do the following steps to create a GSLB site group with ADC instances:

Go to Infrastructure > Instances > GSLB Site Group.
Click Add.
Specify a name for the GSLB site group.
Select the instances that you want to add in the GSLB site group. These instances act as sites in the group.
Select at least one site and click Make Active Site.

Instance that is set to priority 1 becomes the primary node. You can reorder the priority of the active sites. Select the lower priority instance and click Move up priority.
Click Create.

In Infrastructure > Network Functions > GSLB, the GUI displays the entities only from the primary ADC node of the GSLB site group.
