ltm ve network interface driver
we have some older LTM VE devices running in v188.8.131.52, for support reasons we are upgrading them to v14 & later to v15. (LTM upgrade path )
They are running on vmware ESX v7 (so higher than 6.7).
When we tried to upgrade to v184.108.40.206 as a first step in going to v15, we lost all connectivity to this system. Even our mgmt interface was not responding anymore (ssh or https). When accessing over a vmware console, we could see the config was loaded and running in v14. And the interfaces were still present but not able to send any communication over any interface.
At the end we used the switchboot command for returning to old version v12.
I'm aware of several article like https://my.f5.com/manage/s/article/K74921042 concerning network driver to be updated. But when we try to perform these "tmctl -d blade tmm/device_probed" command then i'm getting an error "tmctl: tmm/device_probed: No such table".
Can anyone tell us why we are seeing this error on tmctl command ? i know we need to upgrade , and we need to check the network driver after doing this. But if i can't check network drivers , how can i know if they need to be updated as described in the article.
any suggestion is welcome.
