Troubleshooting PowerMax Driver
Symptoms Prevention, Resolution or Workaround
kubectl describe pod powermax-controller-<xyz> –n <namespace> indicates that the driver image could not be loaded You may need to put an insecure-registries entry in /etc/docker/daemon.json or log in to the docker registry
kubectl logs powermax-controller-<xyz> –n <namespace> driver logs show that the driver cannot authenticate Check your secret’s username and password
kubectl logs powermax-controller-<xyz> –n <namespace> driver logs show that the driver failed to connect to the U4P because it could not verify the certificates Check the powermax-certs secret and ensure it is not empty or it has the valid certificates
Driver install or upgrade fails because of an incompatible Kubernetes version, even though the version seems to be within the range of compatibility. For example: Error: UPGRADE FAILED: chart requires kubeVersion: >= 1.23.0 < 1.27.0 which is incompatible with Kubernetes V1.23.11-mirantis-1 If you are using an extended Kubernetes version, please see the helm Chart and use the alternate kubeVersion check that is provided in the comments. Please note that this is not meant to be used to enable the use of pre-release alpha and beta versions, which are not supported.
When a node goes down, the block volumes attached to the node cannot be attached to another node 1. Force delete the pod running on the node that went down
2. Delete the volumeattachment to the node that went down.
Now the volume can be attached to the new node.
When attempting a driver upgrade, you see: spec.fsGroupPolicy: Invalid value: "xxx": field is immutable You cannot upgrade between drivers with different fsGroupPolicies. See upgrade documentation for more details
Ater the migration group is in “migrated” state but unable to move to “commit ready” state because the new paths are not being discovered on the cluster nodes. Run the following commands manually on the cluster nodes rescan-scsi-bus.sh  -i rescan-scsi-bus.sh  -a
Failed to fetch details for array: 000000000000. [Unauthorized]" Please make sure that correct encrypted username and password in secret files are used, also ensure whether the RBAC is enabled for the user
Error looking up volume for idempotence check: Not Found or Get Volume step fails for: (000000000000) symID with error (Invalid Response from API) Make sure that Unisphere endpoint doesn’t end with front slash
FailedPrecondition desc = no topology keys could be generate Make sure that FC or iSCSI connectivity to the arrays are proper
CreateHost failed with error initiator is already part of different host. Update modifyHostName to true in values.yaml Or Remove the initiator from existing host 
kubectl logs powermax-controller-<xyz> –n <namespace> driver logs says connection refused and the reverseproxy logs says “Failed to setup server.(secrets "secret-name" not found)” Make sure the given secret exist on the cluster 
nodestage is failing with error Error invalid IQN Target iqn.EMC.0648.SE1F 1. Update initiator name to full default name , ex: iqn.1993-08.org.debian:01:e9afae962192
2.Ensure that the iSCSI initiators are available on all the nodes where the driver node plugin will be installed and it should be full default name.
Volume mount is failing on few OS(ex:VMware Virtual Platform) during node publish with error wrong fs type, bad option, bad superblock 1. Check the multipath configuration(if enabled) 2. Edit Vm Advanced settings->hardware and add the param disk.enableUUID=true and reboot the node
Standby controller pod is in crashloopbackoff state Scale down the replica count of the controller pod’s deployment to 1 using kubectl scale deployment <deployment_name> --replicas=1 -n <driver_namespace>
