Devices are showing disconnected in DSC after V10 to V11.5.1 upgrade.

Team, Recently upgraded one of our VE HA pair from V10.2.4 to V11.5.1 after upgrade devices in device group showing disconnected, we tried the following steps.

 

Reinitialize the trust in both devices and add it back to device group.

 

Delete the device group and recreate device group with new trust.

 

Reboot the device and try the above two methods again.

 

Touch mcpd db , reboot device and try the above methods.

 

But still we are facing the same issue, we have a case with f5 1-1728657381 after 48hr there is no response from F5, I never faced such poor support from F5 

    Hi

     

    A few thoughts

     

    Are you using a dedicated HA VLAN. Do you have connectivity on this VLAN, can you ping?

     

    Does the Self IP that you are using for HA have the correct port lockdown setting? Set to Allow Default to be sure, you can harden this later if required

     

    Under Devices, has the Configsync and Device Connectivity been configured correctly on both devices? Using IPs from the correct VLAN

     

    Does the device cert on each box look OK - is it in date etc

     

    If any of these need changing then do so and then re-establish the trust between the devices and redo the device group

    We don't have dedicated HA vlan, yes we are able to ping those devices,

     

    lockdown setting is allow default,

     

    yes ips are correct and f5 also verified the same.

     

    yes we regenerated the certs on both devices again.
