Complete the following steps to configure the LoadMaster settings:

  1. Log in to the UI of the active LoadMaster.
  2. In the main menu, go to System Configuration > AWS HA Parameters.

  3. Select First HA Mode from the AWS HA Mode drop-down list.
  4. Select the desired option in the Switch to Preferred Server drop-down list:
    • No Preferred Host: Each unit takes over when the other unit fails. No switchover is performed when the partner is restarted.
    • Prefer First: The HA1 (active) unit always takes over. This is the default option.
  5. Enter the IP address of the standby LoadMaster in the Partner Name/IP text box and click Set Partner Name/IP.
  6. Enter the health check port selected earlier in the Health Check Port text box and click Set Health Check Port.
  7. If using a multi-arm configuration, select the Health Check on All Interfaces check box.
    Note: If this option is disabled, the health check listens on the primary eth0 address.
  8. Log in to the UI of the standby LoadMaster.
  9. In the main menu, go to AWS HA Parameters.

  10. Select Second HA Mode from the AWS HA Mode drop-down list.
  11. Enter the IP address of the active LoadMaster in the Partner Name/IP text box and click Set Partner Name/IP.
  12. Enter the health check port selected earlier in the Health Check Port text box and click Set Health Check Port.
    Note: The Health Check Port must be the same on both the active and standby units in order for HA to function correctly.
  13. If using a multi-arm configuration, select the Health Check on All Interfaces check box.
Note: If this option is disabled, the health check listens on the primary eth0 address.

In the Amazon EC2 console, go to the ELB and select the Instances tab. The active instance should be marked as InService. The standby instance should be marked as OutOfService.

In the LoadMaster, set up a HTTP and HTTPS Virtual Service with Real Servers. These should then be available using the ELB Domain and they should properly fail over.

If a unit is in standby mode, WUI access is restricted to Local Administration only. Full WUI access is available if the unit is in an active or unchecked state.
