  • 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.
  • Note 2 If a container platform is deployed on a virtualization platform, you are advised to use the iSCSI protocol when connecting to SAN storage. If the customer requires the FC, NVMe over FC, or NVMe over RoCE protocol, the virtualization platform needs to be configured. In this case, the customer’s virtualization team needs to provide technical support.
  • Note 3: If NVMe over RoCE or NVMe over FC is used, the version of the nvme-cli tool on worker nodes ranges from 1.9 to 1.16. To query the version, run the nvme version command.
  • Note 4: Only OceanStor/OceanStor Dorado 6.1.0 and later versions support NFS. Only OceanStor/OceanStor Dorado 6.1.3 and later versions support NFS 4.1. OceanStor/OceanStor Dorado 6.1.7 and later versions support NFS over RDMA. OceanStor/OceanStor Dorado 6.1.8 and later versions support NFS 4.2.
  • Note 5: OceanStor Dorado 6.1.7 and later versions support NFS+.
  • Note 6: The provisioned PVC whose volumeType is lun and accessModes is ReadOnlyMany does not support capacity expansion.
  • Note 7: Only system users can configure QoS.
  • Note 8: Only the active-active (AA) mode is supported.
  • Note 9: Only OceanStor/OceanStor Dorado 6.1.3 and later versions support multi-tenant.
