If I am reading this right, I have both IDE (root) and AHCI (data) pools. So
they are using AHCI.
pci-ide, instance #0 (driver name: pci-ide)
ide, instance #0 (driver name: ata)
cmdk, instance #0 (driver name: cmdk)
cmdk, instance #2 (driver name: cmdk)
ide (driver name: ata)
pci15d9,7980, instance #0 (driver name: ahci)
disk, instance #5 (driver name: sd)
disk, instance #6 (driver name: sd)
disk, instance #7 (driver name: sd)
disk, instance #8 (driver name: sd)
