frodr Posted November 7, 2019 Share Posted November 7, 2019 (edited) Hi, I am currently adding 2 nvme ssd`s to the current 2 nvme ssd`s (on separate PCIe cards), now all mounted on a Asus Hyper M.2x16 V2. Unraid is just recognising 1 ssd. I have been running the Asus card earlier without problems. It is activity on all 4 ssd`s when according to there led lights on the card. I have tried PCIe ACS Override Multifunction, Downstream and Both (and none), but no luck. I also tried setting the PCIe slot from Uefi to Legacy, no change. I am running out of ideas why this happens. Can anyone name possible reasons why Unraid don't recognise the drives? Best... Supermicro X11DAI-N, version 1.02 | AMI 3.1 | dual Xeon Silver 4116 | 64 MB RAM | Cache: 2 x nvme ssd in RAID 1 to 4 x nvme ssd on Asus Hyper M.2x16 V2 l Unraid 6.72 l Quadro RTX4000 for Plex docker l RTX 2080 for Win kvm l Samsung 970 Pro as second ssd for Win kvm l Asmedia PCIe USB card. syslog-4.txt Edited November 7, 2019 by frodr Quote Link to comment
