Updating the huawei-csi-controller or huawei-csi-node Service

Perform this operation when you need to update the huawei-csi-controller or huawei-csi-node service, for example, changing the number of copies for the huawei-csi-controller service.

Procedure

Use a remote access tool, such as PuTTY, to log in to any master node in the Kubernetes cluster through the management IP address.
Go to the /helm/esdk directory and run the following command to obtain the original service configuration file. helm-huawei-csi indicates the Helm chart name specified during the installation of the earlier version, and huawei-csi indicates the Helm chart namespace specified during the installation of the earlier version. For details about the component package path, see Table 1.
```
helm get values helm-huawei-csi -n huawei-csi -a > ./update-values.yaml
```
Run the vi update-values.yaml command to open the file obtained in 2 and modify the configuration items by referring to Parameters in the values.yaml File of Helm. After the modification, press Esc and enter :wq! to save the modification.

Run the following command to update Huawei CSI services.

helm upgrade helm-huawei-csi ./ -n huawei-csi  -f ./update-values.yaml
