Backup server functionality
When the primary server is functioning normally, the backup server monitors the primary server every two minutes. If you check the status of the backup server in monitoring mode, no licenses appear in the License pool.
When a malfunction is detected at the primary server, the backup server provides licenses within one minute. Any licenses that were previously administered by the primary server are now listed in the license pool. This is an easy way to confirm that the backup server is verifying licenses.
When the backup server detects that the primary server has recovered, it returns to monitoring mode.
