on a nodepool with (kubevirt provider) Autoscaling Enabled, "oc scale nodepool" command is disabling Autoscaling, but leaves an invalid configuration with Autoscaling info that should have been cleared.

      happens all the time  

The detailed steps & fix are in this ticket, seems the fix is working for agent provider only, should behave the same for all providers.

on kubevirt cluster :
 [kni@ocp-edge119 ocp-edge-auto_cluster]$ oc get nodepool -A -o wide --kubeconfig ~/clusterconfigs/auth/hub-kubeconfig
NAMESPACE   NAME      CLUSTER   DESIRED NODES   CURRENT NODES   AUTOSCALING   AUTOREPAIR   VERSION   UPDATINGVERSION   UPDATINGCONFIG   MESSAGE
clusters    hyper-1   hyper-1                   1               True          False        4.14.20                                      Minimum availability requires 2 replicas, current 1 available

[kni@ocp-edge119 ocp-edge-auto_cluster]$ oc scale nodepool/hyper-1 --namespace clusters --kubeconfig ~/clusterconfigs/auth/hub-kubeconfig --replicas=4
nodepool.hypershift.openshift.io/hyper-1 scaled

nodepool.hypershift.openshift.io/hyper-1 scaled
   

scaling when autoscaling is enabled is no permitted because it results in a none valid configuration.     

    Relates to this fix that covers agent provider, should be implemented for all providers the same:
