My drives are not showing up when connected to my Vantec 4-Channel 6-Port SATA 6GB/S PCIe RAID Host Card with HyperDuo Technology (UGT-ST644R. When i go to System Devices i can see the controller in a IOMMU group.
IOMMU group 10:[8086:8c56] 00:1f.0 ISA bridge: Intel Corporation C226 Series Chipset Family Server Advanced SKU LPC Controller (rev 05)
[8086:8c02] 00:1f.2 SATA controller: Intel Corporation 8 Series/C220 Series Chipset Family 6-port SATA Controller 1 [AHCI mode] (rev 05)
[8086:8c22] 00:1f.3 SMBus: Intel Corporation 8 Series/C220 Series Chipset Family SMBus Controller (rev 05)
But when i go to add the disk to the array it doesnt see them. Can someone please hel;
I can disable vt-d but i am unfamiliar with adding iommu=pt in the syslinux.conf. Can you explain how to do that or point to a place that can?
