DSC is not coming up for LTM VEs after initial setup

    The answer to my initial question - yes, it is possible to configure DSC with VE v13, at least, using LAB license. But this requires 8 GB of RAM and 4 CPUs per VE. Not sure if this can be performed with Trial or Evaluation licenses as I have no possibility to test this.

UPDATE: I have tested the same configuration with TMOS v12.1.3.7 and everything went fine. The cluster was successfully formed and configuration synced. Also I have checked v14.0.0.2 - configuration is not synchronized between devices. What I have spotted is that the output from "tmsh run /cm watch-devicegroup-device" and other "tmsh run /cm watch *" commands state "Incompatible Version", despite both appliances use the same TMOS SW version. So it seems currently neither v13.x nor v14.x are able to form DCS and sync configuration successfully.

 

Below reside logs from a standby virtual appliance:
