- For details about the Windows versions, see the Huawei Storage Interoperability Navigator.
- If a LUN has been mapped to a host, you must restart the host for the configuration to take effect after you modify Host Access Mode. If you map the LUN for the first time, restart is not needed.
- The information displayed on the GUI may vary slightly with the product version.
Host Configuration
Install, configure, and use UltraPath by following instructions in the OceanStor UltraPath for Windows User Guide.
- If NPIV-enabled Windows VMs will directly access LUNs of the storage system, disable the alarm function of UltraPath after installing UltraPath.
- In a Windows server cluster, if NPIV-enabled Hyper-V VMs have been migrated (in online or fast mode) between servers, the NPIV paths managed by UltraPath will become disordered due to Windows mechanism defects. To ensure that services on Hyper-V VMs will not be interrupted, you are advised to run the upadm set npiv_strategy={ off | check | force-check | update} command to set the path detection mode to update in this scenario.
