Hi,
I'm building a new ESXi4 server with VT-x and VT-d capabilties and an LSI megaraid 8344ELP raid controller. The disks work fine with VT-d disabled in the BIOS but after turning on VT-d, ESXi is unable to access the disks.
After loading the vtd module the following errors appear in the messages log:
WARNING: VTD: 1756: IOMMU Unit # 3: R/W = 0, Device 033:08.0 Faulting PA = 0x214ae9000 Fault Reason = 2
LVM: 3543: Could not open device naa.600605b0003de930121870e096eb4972:1, vol megaraid_sas disks inaccessible after loading vtd module.: No such partition on target
Disk access can be restored by unloading the vtd module and is lost again when the module is loaded.
One of the reasons I want to upgrade to ESXi4 is because I want to use DirectPath so turning VT-d off is not really an option.
Is there any way I can make VT-d work together with my raid controller?
Thanks,
Thijs.
