VM can not add Fiber Channel Adapter

Hi There,
We have one Failover Cluster for Hyper-V VMs running on Windows Server 2012R2. Everything working well but one thing. Today, I try to create Hyper-V VM server, everything normal also but I can't not add Fiber Channel Adapter for VM server. I click on "Add Hardware" the option Fiber Channel Adapter grayed out.
Have anyone faced same issue with me? I have tried some actions but still can not. It is production system so any safeties way to fix this issue.
Thank you in advance!

Hi,

When you add the adapter for the VM, do you shut down the VM? When we add it, the VM should be offline.

Thanks for your time!
Best Regards,
Anne

Hi,

Do you perform the operation on the owner node of the VM?

Hi,
One thing I found, Generation 1 VM still can add Fiber Channel Adapter but Generation 2 can't.

how many fibre channel adapters available you get when you place your cursor over fibre channel adapter greyed?

If you place the cursor over fibre channel adapter greyed and wait, it shows how many fibre adapter are available.
if it shows 0 available adapters and you don't have any adapter configured in the virtual machine, could be a driver problem.

Problem is, the previous added FC servers still working fine but can't create new server with FC.
