Refresh the database after a BIG-IQ in an auto failover HA configuration comes back online

You can select the HA error alarm from the
Monitoring
ALERTS & NOTIFICATIONS
Monitoring ALERTS & NOTIFICATIONS
General Settings
screen to notify you if a BIG-IQ in your HA auto failover configuration becomes unresponsive. If an issue occurs, an HA Alert appears on the Alert Properties screen as
HA status has changed from OPERATIONAL to FAILED
.
If the one of the BIG-IQ systems becomes inactive, the active BIG-IQ continues to manage traffic. If the inactive BIG-IQ becomes healthy again in less than 3 hours, it automatically rejoins the BIG-IQ auto failover HA configuration with no required intervention from you. But if the BIG-IQ has been down for over 3 hours, you'll need to re-sync the database between the active BIG-IQ and the newly-activated standby BIG-IQ.
If the BIG-IQ auto failover HA configuration has been inoperable for over 3 hours, you must recreate the configuration by adding a standby BIG-IQ and a BIG-IQ DCD quorum back to the standalone, active BIG-IQ.
  1. From the active BIG-IQ, at the top of the screen, click
    System
    .
  2. On the left, click
    BIG-IQ HA
    .
  3. Click the
    BIG-IQ HA Settings
    button.
  4. Click the
    Repair Database
    button to resynchronize the database between the active and standby BIG-IQ systems.
    This button displays only if the database needs to resynchronized.
  5. Click the
    Save & Close
    button.
