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
- Upgrade the Unisphere to have 10.0 endpoint support.Please find the instructions here.
- Update the
my-powermax-settings.yaml
to have endpoint with 10.0 support.
Update Driver from v2.10.1 to v2.11.0 using Helm
Steps
- Run
git clone -b v2.11.0 https://github.com/dell/csi-powermax.git
to clone the git repository and get the driver. - Update the values file as needed.
- 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 thecsi-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 thehelm-charts
repository present in thecsi-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.
