Hi,
We are getting an error in k8s when we try to attach a volume from Dell EMC PowerStore to a pod in a StatefulSet application, do you have an idea why?
What we`ve done:
- Deployment of CSI driver was successfully. (Initialization of plugin pods on Kubernetes nodes and initiator group for PowerStore storage)
- We tried to test PVCs and StatefulSet, volumes were successfully created but the pods remain in Creating state and from running command kubctl describe the pod we get the below error:
Warning FailedAttachVolume 4m35s (x45 over 79m) attachdetach-controller AttachVolume.Attach failed for volume "csi-a571c6d7b1" : rpc error: code = Internal desc = Could not get iscsi iscsiTargets: can't get iscsi target address
Warning FailedMount 3m2s (x29 over 77m) kubelet, cl-k4s-k8s-node-nf-1 Unable to attach or mount volumes: unmounted volumes=[pvol1], unattached volumes=[pvol1 powerstoretest-token-tkvng]: timed out waiting for the condition
If we run on the worker node iscsiadm -m session we get the active sessions to PowerStore.
iscsiadm -m session

Thanks in advance!
Hi Stefan,
Do you mind connecting the slack channel for Container Storage Module here : https://dellemccsm.slack.com/
If you need an invite you can ask for it here : http://del.ly/Slack_request
There is a broader audience to answer your question.
We will need the logs from both the controller and driver to understand why the iscsi target are not discovered.
Thanks

The error was not posted. when you do a get pv and get pvc do you see any errors or are they bound?
