The following is a list of Hyper-V features that are compatible with virtual Fibre Channel.
The following is a list of Hyper-V features that are not compatible with virtual Fibre Channel
· UI: “This device or driver does not support virtual Fibre Channel.”
· Event Log: Warning 32170 logged by VMMS at startup
· WMI: Msvm_ExternalFcPort property IsHyperVCapable = False upon running the following query :
· gwmi -n root\virtualization\v2 Msvm_ExternalFcPort -Property InstanceId, WWPN, IsHyperVCapable
· If Querying for MSFC_FibrePortNPIVMethodsEx or MSFC_FibrePortNPIVAttributes returns Invalid Class then Rebuild portion of WMI store Mofcomp /i c:\windows\system32\wbem\npivwmi.mof
· If the HBA is from Emulex, use OneCommand to set Host Driver Parameter “EnableNPIV” to Enabled, then reboot
· If the above remediation steps are not applicable or do not work, contact the server or HBA vendor for driver, firmware updates
· HBA failing to remove virtual port
· Host unresponsiveness
· The failure of the HBA to remove the virtual port can be confirmed by:
o Verifying that no running VM is using same WWPN
o Checking for virtual port removal failures in event log (see below in example event logs)
· Mitigation: Remove the port using HBA management tools or by using a WMI call or by rebooting the host. Escalate the issue with the HBA and fabric vendors
· If a host hang is confirmed by identifying fabric ports using fabric management tools, reboot connected host or disable the offending fabric port
· WWPN “A” and “B” not included in zones and masking sets
· Virtual SAN on remote node missing
· Destination host has fewer paths to target than the origin host
· LUNs associated with the VM do not appear as available at the destination node
· Analyze the event logs on the destination:
o If Virtual SAN missing, log will have specific details. Create SAN to fix
o If LUNs are missing:
§ Double check Virtual SAN’s assigned HBAs are connected to same fabric
§ Confirm WWPN “A” and “B” are included in zones and masking sets
§ Confirm the number of paths to target will be the same
