Dell unity csi driver for kubernetes issues

Hello,

We are using dell unity csi driver with rancher(kubernetes)

However, the pod registration fails for the worker nodes,and in the unity UI I see the initiators "Initiators does not have any logged in initiator path"

This happens to all worker nodes.

 k get pods -n unity

I tried deleting the initiators for the worker nodes and recreating the pods by running kubectl get pods -n unity --no-headers=true | awk '/unity-/{print 1}'| xargs kubectl delete -n unity pod

But it didn't help and it keeps crashing. How do I fix this?
