Hyper-V fiber channel unable to present Luns to guest VM

Question

Hi,

We experienced an issue when configuring virtual fiber adapter

When the the VM powered on it took sometime to start
and an event log will be written:

Log Name: Microsoft-Windows-Hyper-V-SynthFC-Admin
Source: Microsoft-Windows-Hyper-V-SynthFcVdev
Date: 15/9/2021 2:13:08 PM
Event ID: 32213
Task Category: None
Level: Warning

Description:
'savdalfc01': No LUNs have appeared for Synthetic Fibre Channel HBA
Fibre Channel Adapter (BB50C162-40E7-412B-AB06-B34104CF6D17). The
VM has been started after the timeout period (90 seconds). Please
review the LUN mappings for the virtual port. (Virtual machine ID
1F2AA062-7677-45C0-86F6-643C33796A9D)

I logged in to San switch to add WWPNs for each adapter that assigned to the virtual machine but I received the same warning and no luns appeared inside the VM. But it appears in the Hyper-V host

Hello @Ahmed Essam

Virtual Fiber Channel is not an easy thing to troubleshoot and maybe opening a ticket with Microsoft Support will save time in your deployment.

My best shot without more details would be the next article, that describes different tests and approaches to the issue. Even if it doesn't resolve it, for sure will provide a better overview of what works and what fails.
