PowerMax

You can upgrade CSI Driver for Dell PowerMax using Helm or Dell CSI 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 v2.3 to v2.4 using Helm

Steps

  1. Run git clone -b v2.4.0 https://github.com/dell/csi-powermax.git to clone the git repository and get the v2.4 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.

NOTE:

  • 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
...
