Configuring Multi-Appliance Instance-Level HA

This configuration assumes an established appliance-to-appliance HA pairing as described in Setting Up Unit-to-Unit HA.

To establish an HA pair of instances residing on different NSsp appliances

1. First establish unit-to-unit pairing as described in Setting Up Unit-to-Unit HA.
2. Have at least one dedicated unused physical port connected on both the NSsp HA unit, to be used for the Multi-instances HA control interface and HA Data interface. Although we recommend two dedicated unused ports, one for the HA control interface and one for the HA data interface.
3. Upload instance firmware on both primary and secondary appliances. After the firmware is uploaded successfully on both the primary and secondary units verify that the Running column on the DEVICE | Instance > Firmware page on the Active unit shows as BOTH.

4. Ensure that both Primary and Secondary Instances are Registered with MySonicWall.com and both units have Instance Licenses from their respective Instance License page.
5. Repeat Step a to Step s for adding virtual instance HA pair on ACTIVE NSsp appliance as mentioned the Instance HA pair on a standalone NSsp. Refer to Instance HA Pair on a Standalone NSsp Node. Ensure that Primary Instance License is selected from the Primary NSsp Instance License page, and Secondary Instance License is selected from the Secondary NSsp Instance License page.
6. Note that the residence of the instance is announced in the following figure, Residence Announcement.

7. Verify the addition of a Primary and a Secondary Instance from the Multi-Instance on the Instances page.
