isilon-node fails with no such host in vSphere with Tanzu 7U2 (TKC)

 Hi,

I believe CSI driver for isilon doesn't officially support Tanzu,  however we are trying to test and see if it works as we need it for a use case with PV mode RWX and on Dell isilon storage.

Environment: vSphere with Tanzu (7U2), K8S: 1.19.7 (VM OS: Photon OS 3.0)

csi-powerscale: We tried with 1.5.0 & 1.4.0.

Getting the below error, Any pointers on why is this error, what is it expected to get out of this lookup?

Is there any workaround to solve this?

Error:
