Hi Aviv,

the message "awaiting the initial config sync" typically indicates that units never were in synced state.

(Maybe due to re-creating the sync-failover device group.)

Please check both units for the device settings (failover, config sync, mirroring).

Local self IPs need to be used for all these properties and the port lockdown should be set to "allow default". Both units are added to the new sync-failover device group?

Device trust is established bi-directional (check device list on both machines).

Make sure both units are on same time ("
ntpq -p
").

Watch the log file for error messages during config sync:

tail -f /var/log/ltm

Thanks, Stephan
