Before you continue

You should be familiar with the following before continuing.
  • Understand and experience configuring Fibre Channel technologies.
  • Understand and experience configuring Hyper-V.
  • Familiarity with reading Windows Server event logs.

Introduction

Virtual Fibre Channel allows Hyper-V users to run clustered workload within a Virtual Machine while leveraging their existing Fibre Channel (FC) Storage Area Network (SAN) investments.
N Port ID Virtualization (NPIV) simplifies management and the use of multipathing through MPIO facilitates better resiliency and higher performance.

Requirements for Virtual Fibre Channel

  • One or more installation of Windows Server 2012 with Hyper-V role installed.
  • A computer with one or more Fibre Channel host bus adapters (HBAs) that have an updated HBA drive that supports virtual Fibre Channel.
  • The HBA must support N_Port ID Virtualization (NPIV).
  •  Virtual machines configured to use a virtual Fibre Channel adapter, must be running one of the following guest operating systems:
    • Windows Server 2008
    • Windows Server 2008 R2
    • Windows Server 2012
    • Windows Server 2012 R2 Preview
  • Storage accessed through a virtual Fibre Channel adapter supports devices that resent logical units.

Limitations

  • Virtual Fibre Channel does not work with client SKU’s of Windows.
  • Each virtual machine can have no more than 4 virtual HBAs.
  • Hardware may limit the number of virtual ports per physical HBA. This would restrict the number of virtual machines that can be associated with each physical HBA installed on the host.
  • Hardware may limit the number of logical units per physical port. 

Interoperability with other Hyper-V features

The following is a list of Hyper-V features that are compatible with virtual Fibre Channel.

  • Live migration
  • Quick migration
  • Virtual machine Save and Restore
  • Virtual machine Pause and Resume
  • Virtual machine Export and Import
    • Note: The storage associated with the virtual machine in a Fibre Channel SAN are not part of the Export / Import operations. The operations will be shallow and restricted to the virtual machine and its configuration state.
  • Host initiated backup
    • When the incremental backup change tracking VSSD setting is turned off (default) the backup will succeed with a warming message in the event log.
    • When the incremental backup change tracking VSSD setting is turned on, the backup operation will fail.

The following is a list of Hyper-V features that are not compatible with virtual Fibre Channel

  • Checkpoints (formerly known as Snapshots)
  • Hyper-V Replica

Is Fibre Channel over Ethernet (FCoE) supported?

Yes, FCoE is supported with a certified Converged Network Adapter (CNA).  

What is the virtual port creation process?

The following are the steps taken by Hyper-V when creating a virtual port after a virtual Fibre Channel adapter has a virtual SAN configured:
  • Hyper-V calls the HBA driver to create a virtual port.
  • A physical port is assigned to the virtual SAN is performed using a round robin scheme.
  • If a virtual port fails to be brought online using the assigned physical port, another physical port will be will be attempted.
  • If the virtual machine cannot successfully connect to the virtual port, the virtual machine will fail to start.
  • Once a virtual port has successfully connected to the physical port, Hyper-V removes that virtual port from the list of ports available until the virtual machine releases it. 

Tape library support

Virtual tape libraries configured with a virtual Fibre Channel adapter are only supported when using System Center Data Protection Manager 2012 R2 U3 or later with certified hardware. For more information, see Compatible Tape Libraries for System Center 2012 DPM. To determine if a tape library is supported by virtual Fibre Channel adapter, contact the tape library hardware vendor or run the DPM Tape Library Compatibility Test tool. For additional information about the DPM Tape Library Compatibility Test took, see Verify tape library compatibility.


Sample event log entries

The following section are examples of event log entries that can be created during various states of a virtual machine.

Virtual machine startup

Virtual machine startup involves a transition from the stopped state to the running state through to the starting state.
For a virtual machine with virtual Fibre Channel enabled, the port creation process is initiated when the virtual machine enters the starting state. Each Logical unit that is discovered generates an event that is logged to the event log. A bus rescan is performed if no Logical Units are discovered within a stipulated timeout window. The default timeout windows is 60 seconds.

Virtual machine running

When a virtual machine is running, the addition and removal of logical units generates an event that is logged in the event log (example below). The new logical units are unmasked to the virtual machine. Link state changes (link loss/gain) will cause the HBA to log logical unit removal and additions.

Virtual machine power off

When a virtual machine is powered off (shutdown), Hyper-V removes the logical units associated with virtual ports and deletes the virtual ports. The virtual ports can now be used by another virtual machine. Events correspond to each logical unit do not occur in the event log.

Virtual machine save

When a virtual machine is saved, all I/O operations on the LUNs exposed to the virtual Fibre Channel adapter are queued and are allowed to complete before the virtual machine is put into a saved state. The list of LUNs exposed to the Virtual FC HBA is stored in the saved state file. The virtual ports associated with the virtual machine are deleted.

Virtual machine pause

When the virtual machine state transitions to a pause or pause critical state, the virtual machines virtual ports will be maintained on the host. Pending I/Os completion on the host will be sent to the target and their completion status will be saved in the host’s memory.
There are no event log entries when a virtual machine enters a pause or pause critical state for virtual Fibre Channel. 

Virtual machine reset

A VM reset operation is comprised of a power-off operation followed by startup.

Virtual machine restore

When a virtual machine is restored from its saved state, Hyper-V resumes the virtual machine even if LUN’s are unavailable.
After a virtual port is created on a physical HBA, unmasked LUNs may take non-deterministic amounts of time to appear on the host. The successful discovery of each available LUN is associated with an event that is logged in the event log. If LUN’s fail to appear as available within a stipulated timeout window, a timeout occurs and the list of unavailable LUNs are logged in the event log (example below).

Virtual Fibre Channel and Live Migration

Before a virtual machine that has a virtual Fibre Channel adapter configured can be moved (migrated) to another host, Hyper-V checks to ensure that all of the SAN resources used by virtual machine are accessible from the destination host. This behavior also ensures that the SCSI reservation states are unaffected after the live migration occurs, to avoid any cluster failovers.
To work around the time sensitivity of blackout times in live migration, each virtual Fibre Channel port needs to be configured with 2 sets of World Wide names (2 WWPN’s and WWNN’s). Only one of them is active on the source machine, and the other one is used when the virtual machine is migrated to the target machine. Hyper-V automatically alternates between the two address pairs during a live migration.
As a part of preliminary live migration checks, the virtual SAN on the target host is compared with the same name as that of the source host. The operation that involves checking for LUN connectivity using the second configured WWN pair for the virtual machine is performed after the virtual machine is migrated to the destination host and power-on is attempted on the destination host. If this check fails, the Live Migration operation will fail.

Virtual Fibre Channel and Quick Migration

A Quick Migration is essentially a virtual machine Save on the source host followed by a virtual machine Restore operation on the destination host.
On the source host, all I/O operations on the LUNs exposed to the Virtual Fibre Channel adapter are queued and all outstanding I/O on all the LUNs exposed to the virtual Fibre Channel adapter are allowed to complete. The list of LUNs exposed to the virtual Fibre Channel adapter are stored in the saved state file. Subsequently the virtual ports associated with the virtual machine are torn down.
On the destination host, a virtual port is created on a physical HBA. Unmasked LUNs may take non-deterministic amounts of time to appear on the host. The successful discovery of each available LUN is associated with an event that is logged in the event log. If LUN’s fail to appear as available within a stipulated timeout window, a timeout occurs and the list of unavailable LUNs are logged in the event log.
It is important to note that quick migration succeeds even if LUN’s are unavailable on the destination host, which is not the behavior when using live migration.
 

Troubleshooting samples

 
Symptom
Possible Cause
Troubleshooting steps
Incompatible / Unsupported HBA error
Driver, firmware combination does not implement NPIV
 
Unsupported HBA’s are confirmed by any one of following:

·         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

 
Remediation

·         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

 
VM fails to start Attempts to create a Virtual Port failed for all physical ports assigned to Virtual SAN

 Remediation

- Check the status of each HBA assigned to the virtual SAN and repair if necessary

VM fails to start
Virtual Port creation failure because the WWPN is still in use because of:

·         HBA failing to remove virtual port

·         Host unresponsiveness

 
 
 
 
Evidence: Event Log events (see below in example logs), WWPN listed in fabric’s nameserver
 

·         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

'TestVM' failed to start. (Virtual machine ID 12BE2D01-D693-4488-AA5F-3715CBDA4F10)
 
 
Live Migration fails on destination node
 

·         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
