i followed the steps from this link :

https://scod.hpedev.io/learn/persistent_storage/index.html#installing_the_helm_chart

all was fine and the PVC got created in our namespace and it is bound, and i can also see the PVC created on Nimble Storage
however whenever i install any pod like nginx, it get's stuck and i get the below error when launching the pod :

Hey @husseinallaw this error indicates that the control plane is working fine but the data path is not working, meaning that the device can not be discovered on the node it's being presented to. Could you describe your environment?

• Worker node OS
• Worker node compute type (virtual/bare-metal)
• Data protocol (FC/iSCSI)
• CSI Driver version

Hello,
I have the same issue.

• Worker node is : ubuntu
• Virtual (proxmox)
• data protocol is accessProtocol: "iscsi"
• csi driver : 2.4 (install by helm chart)

The array is a nimble strorage model, version 6.0

Can you help me, or where can I find some logs to help me ?

Thanks :) !!!
