Elrith Posted January 6, 2020 Share Posted January 6, 2020 (edited) Hello Gents, I have recently purchased this Quad NVME card and I'm trying to set it all up with Unraid The spec: X10DRG-Q MB 8*16GB DDR4 2666 (running at 2133) LSI 9211-4i 1*6TB HGST SAS 2*2TB Samsung SAS 3*1TB Seagate SATA onboard 1*480G Intel SSD (cache) 1*WD BLUE NVME 500G 3*760P Intel NVME Asus Hyper x16 Corsair RM1000X PSU RTX 2080 Creative sound blaster Z I've enabled bifurcation from x16 => x4x4x4x4 The problem: The system is booting up properly, I'm able to see 4 nvme drives in Unraid, happy days. I'm starting my array and then the whole server hangs. After this I'm restarting and the server hangs during the boot sequence inside the BIOS. What I've tried: 3.1 and 3.1C bios 3xNVMES I/O non posted prefetch enabled Disabling as many devices as possible from the BIOS Setting the Asus card PCIE port for UEFI Booting unraid in Legacy/UEFI Moving the card to a different slot What worked partially but hinders me from seeing all 4 drives: Not enabling bifurcation allows me to see 1 NVME drive but the system is stable. IPMI is reporting the following error whenever the hang occurs: #0x00 ProcessorConfiguration Error (DMI) - Assertion The system has always been stable, no crashes or freezes. I don't think I'm running out of PCI lanes, i thought about this possibility. At the same time writing this I'm writing an email to supermicro. I hope to pick your brains and see what are your suggestions. Thank you for taking the time to go through this post. Edited January 6, 2020 by Elrith Quote Link to comment
Elrith Posted January 7, 2020 Author Share Posted January 7, 2020 Fixed* The WD blue NVME drive was the one at fault. The array is working fine now with the Intel ones. Quote Link to comment
