for a customer deployment, we wanted CSI for NetApp EF570 storage device (SANtricity/ISCSI) in our k8s cluster (v1.27.10/ubuntu24.04 OS).
We installed trident v25.0 but documentation said E series are not supported from trident v21.07. So we downgraded the trident to v21.04 where E-series is supported. But the trident-operator says Kubernetes v1.27.10 is not supported in trident v21.04
