PowerMax

You can upgrade CSI Driver for Dell PowerMax using Helm or Dell CSM Operator.

Note: CSI Driver for PowerMax v2.4.0 requires 10.0 REST endpoint support of Unisphere.

Updating the CSI Driver to use 10.0 Unisphere

1. Upgrade the Unisphere to have 10.0 endpoint support.Please find the instructions here.
2. Update the my-powermax-settings.yaml to have endpoint with 10.0 support.

Update Driver from v2.11.0 to v2.12.0 using Helm

Steps

1. Run git clone -b v2.12.0 https://github.com/dell/csi-powermax.git to clone the git repository and get the driver.
2. Update the values file as needed.
3. Run the csi-install script with the option --upgrade by running:

   
   cd ../dell-csi-helm-installer && ./csi-install.sh --namespace powermax --values ./my-powermax-settings.yaml --upgrade --helm-charts-version <version>
   

NOTE:

• The parameter --helm-charts-version is optional and if you do not specify the flag, by default the csi-install.sh script will clone the version of the helm chart that is specified in the driver’s csi-install.sh file. If you wish to install the driver using a different version of the helm chart, you need to include this flag. Also, remember to delete the helm-charts repository present in the csi-powermax directory if it was cloned before.

• If you are upgrading from a driver version that was installed using Helm v2, ensure that you install Helm3 before installing the driver.

• To update any installation parameter after the driver has been installed, change the my-powermax-settings.yaml file and run the install script with the option --upgrade, for example:

  
  ./csi-install.sh --namespace powermax --values ./my-powermax-settings.yaml –upgrade
  

• You cannot upgrade between drivers with different fsGroupPolicies. To check the current driver’s fsGroupPolicy, use this command:

  kubectl describe csidriver csi-powermax
  

  and check the “Spec” section:

  ...
  Spec:
    Attach Required:     true
    Fs Group Policy:     ReadWriteOnceWithFSType
    Pod Info On Mount:   false
    Requires Republish:  false
    Storage Capacity:    false
  ...
  

Upgrade using Dell CSM Operator:

Note: Upgrading the Operator does not upgrade the CSI Driver.
