Not all devices sync

I see the status "Not all devices sync" on one on version 11.5 LTM pair. I believe the in version 11 and above the devices are auto sync. I ran a command - load /sys config then this started coming. how to correct that or is it the reason of not sync?

    Can you please share the error during sync(NTP, VLAN, etc).

    As far as I understand the timestamp of the binary will be used to verify the latest config change. The timestamp of the binary file should be updated, if you run a config load from your text based config on both units:

                tmsh load sys config

    This will be followed by config sync:

                tmsh run cm config-sync to-group device-group-failover

    Monitor the related log on both units:

                tail -f /var/log/ltm

    To be on the safe side I recommend to make a config backup on both units first:

            tmsh save sys ucs backup_unit_name

    Time is critical so if you do not have NTP setup strongly recommend this is done.

     

    Ensure 'ConfigSync' addresses are configured correctly (Web GUI: Device Management, Devices, (Self). Device Connectivity, Config Sync) (TMSH: list cm device configsync-ip) Check you can ping/connect between the LTMs on via the configsync ip addresses.

     

    If all ok check the ltm log while forcing a sync, you may need to reset the trust between the LTMs or even re-create the Device Group.
