When deploying content updates to managed
devices when Panorama™ is in a high availability (HA) configuration,
Panorama balances the content update jobs between the HA peers to
decrease the load on each Panorama. In the event that an HA peer
becomes unreachable during the content update, the content update
jobs fail for the managed devices to which the down HA peer would
normally push the content updates. This occurs for both scheduled
and manual content updates. To complete the content update, you must
manually push the content update to those managed devices.
