command clsh cpcfg on tenant velos

Hi , Have you checked that "clsh" really is not present on the tenant's CLI by logging into it and going into bash mode?

The tenants on Velos that are classical BIG-IP are like vCMP quests with a selected  primary blade from the blade cluster etc. For NEXT it is different as it is just extra pods inside the Velos k8s system but no need to go there 🙂 

For the controller and partition CLI even in bash mode I agree that this is the case as now there are 2 controllers and not a Primary blade like with Viprion but you can ssh to different blades as workaround Overview of access to the F5 VELOS system .

For your case as Velos last I checked still does not support upgrade of tenants from the HOST/partition you need to do it from the tenant and you can just see if clsh is present in the tenant CLI bash.
