Note 1: Manage Provisioning is a volume management feature customized by Huawei CSI. This feature allows existing storage resources to be managed by Kubernetes. You are not allowed to manage a storage resource for multiple times and concurrently delete or create a storage resource. When a storage resource is managed by multiple clusters, operations on the managed volume in a single cluster take effect only in the cluster and will not be synchronized to other clusters. Instead, you need to perform these operations on the managed volume in other clusters.
Note 2: Modify Volume is a PVC change feature customized by Huawei CSI. This feature allows a common volume to be changed to a HyperMetro volume. To use this feature, ensure that the connected storage supports the volume HyperMetro feature.
