Performing Manual Split-Brain Recovery

When automatic split-brain recovery is disabled, and split-brain has been detected, the HA status icon on the Overview screen indicates an error on both the active and standby nodes, and a Recover button appears.

Because the data between the two devices are no longer synced after split-brain occurs, you may want to save and compare the data between the two devices, before deciding which device to configure as the active node.

  1. Log on to QNE on one of the devices.
  2. Open HA Manager.
  3. Go to Overview.
  4. Click Recover.

    The Split-Brain Recovery screen appears.

  5. Answer the following question and follow the relevant steps.
