Hi,
Im building a new ESXi 5.5 system on Asus H87i-itx board with Intel i5 Haswell 4670T chip. Mainboard and CPU both support VT-d / DirectPath I/O so far as I can tell, but I have a problem.
In ESXi I can see most devices available for DirectPath I/O passthrough such as Video, Audio, NIC and USB controller, everything is available for DirectPath I/O passthrough except for Lynx Point SATA AHCI controller.
Can anybody help diagnose why the SATA controller is missing, and steps for more detailed debugging ?
Previous Cougar Point AHCI SATA controller is supported in ESXi so why not Lynx Point.
Also, Lynx Point SATA AHCI controller is listed on VMware HCL page here:
VMware Compatibility Guide: I/O Device Search Intel "Lynx Point" Series Chipset 6-Port SATA AHCI 8086:8c02
Strange thing is my ESXi can see the Lynx Point SATA AHCI controller in Storage Adaptors correctly, showing 6 x VMHBA listed, so why does it not appear in passthrough, and not even greyed out ?
Is there any extra diagnostic I can do please tell me ?
Would like to avoid doing physical raw mapping (rdm) if possible, DirectPath I/O Passthrough would be much nicer method. :-)
