Multiple Isilon CRDs defined, but only single a Storage Class created

We’ve run into a curious issue. While we can define multiple CRDs for each Isilon instance, the controller does not seem to be creating Storage Classes for each instance:

$ kubectl get csiisilon
NAME          AGE
rridc02-dev   15m
rridc03-dev   31m

$ kubectl get storageclasses
NAME                                 PROVISIONER              AGE
rridc02-dev-storageclass (default)   csi-isilon.dellemc.com   18m

I confirmed this by removing and republishing rridc03-dev, which resulted in this:

$ kubectl get csiisilon
NAME          AGE
rridc02-dev   32m
rridc03-dev   2s

$ kubectl get storageclasses
NAME                                 PROVISIONER              AGE
rridc03-dev-storageclass (default)   csi-isilon.dellemc.com   4s

The controller seems to only be creating a Storage Class for the last added CSIIsilon CRD.
