Hi,
I've added LSI SAS Megaraid 9286CV RAID card to an ESXI (6.7 with all the updates) and I passed this card through PCI Pass though. So far, so good.
At first I tried to pass this card with it's option ROM, but it seems vSphere EFI's doesn't support this functionality (booting in EFI mode just freezes the VM with the VMware logo), so I created a RAID on the host and when booting this VM with this PCIe card, I can see and install an OS (I tried Windows server 2019)
The problem - the VM machine cannot boot fhis RAID. When I go to the EFI BIOS I see the Windows boot manager, but trying to boot from it always fail.
So as last resort, I've installed the OS on a datastore.
My question: is this issue (unable to boot a VM from vsphere with hardware configured RAID) is known?
Thanks
