Rolling Back Huawei CSI

If CSI fails to be upgraded from 2.x or 3.x to 4.5.0 and needs to be rolled back, uninstall CSI by referring to Uninstalling Huawei CSI Using Helm and then download and install CSI of the source version.

NOTICE:

• During the upgrade or rollback, the existing resources such as PVCs, snapshots, and Pods will run properly and will not affect your service access.
• During the upgrade or rollback, you cannot use Huawei CSI to create new resources or mount or unmount an existing PVC.
• During the upgrade or rollback, do not uninstall the snapshot-dependent component service.
