M2 NVME disk not visible in Unassigned Devices

Recommended Posts

I have installed a 1TB M2 NMVE ADATA Technology Co., Ltd. XPG SX8200 Pro PCIe Gen3x4 M.2 2280 Solid State Drive that is not visible in Unraid unassigned devices. 


In syslog I see these events regarding NMVE:

Mar 29 14:03:17 Freedom kernel: Command line: BOOT_IMAGE=/bzimage nvme_core.default_ps_max_latency_us=0 initrd=/bzroot
Mar 29 14:03:17 Freedom kernel: nvme nvme0: pci function 0000:02:00.0
Mar 29 14:03:17 Freedom kernel: nvme nvme0: Device not ready; aborting initialisation, CSTS=0x0
Mar 29 14:03:17 Freedom kernel: nvme nvme0: Removing after probe failure status: -19


The drive is visible in an IOMMU group.


I have installed the M2 card directly into the motherboard slot and also onto a pcie adapter card with same results.


Does anybody have any ideas on why this isnt visible?
