Bigip HA sync problem

Bigip HA sync Problem

we have 2 Units of f5 ver 12 in HA . someone,by mistake start to create objects and a vs in the standby unit. when he saw that he is in the standby unit he started to create the some objects at the active unit and then he pressed on sync to group with the checkbox of overwrite. since then the standby unit is unsynced and we get this error:

Sync Summary Status Awaiting Initial Sync Summary One or more devices awaiting initial config sync Details

  1. F5-02.com is awaiting the initial config sync
  2. Recommended action: Synchronize F5-01.com to group sync-group
we have tried to recreate the a Sync-Failover Device Group but problem still exist.

Approache:--
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 ("
  1. ntpq -p
").

Watch the log file for error messages during config sync:

  1. tail -f /var/log/ltm
 Ans:--
we deleted all vs &pools & nodes from the standby device and then sync worked perfect
