October 27, 20205 yr Hi everyone, From scanning the forum I realise this appears to be a recurring problem, but would be grateful for some guidance. Having maxed out the six SATA ports on my motherboard, I picked up a PCI-E SATA card to add two additional drives (eight drives is a case limitation). The card is a Ziyituod (https://www.amazon.co.uk/gp/product/B07T8XNQT6/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1), and appears in both the BIOS and UNRAID GUI as “ASMT109x-_Config_0123456789 – 105mb”, but the two drives attached to it do not display in either. They are recently shucked 12tb drives with the correct pins covered. The controller can boot in AHCI mode, IDE mode or “no boot” mode – is that at all relevant? No problems booting the array without the card / additional drives assigned. My system is as follows: Motherboard: ASRock B365M-HDV CPU: Intel Pentium Gold G5400 Is there an obvious solution to this? I've read about the issues with MARVELL controllers, so is the short answer to get a better card, or is there another solution? Grateful for any input people might have.
October 27, 20205 yr That controller has a SATA port multiplier and is not recommended, but it show detect the disks, diags might give some clues.
October 27, 20205 yr Author Thank you for the response. I've attached my syslog. Do you need anything else diagnostic wise? syslog.txt
October 27, 20205 yr When we ask for diagnostics we prefer the full diagnostics (tools -> diagnostics) but for this case the syslog is enough, it appears to be a controller problem/incompatibility, it's only detected as a two port controller, one of them is detecting a virtual device connected, the other no link, since you only need two ports I recommend you replace it with a 2 port Asmedia controller, those work fine.
October 30, 20205 yr Author Thank you for your response. In the meantime I have checked all the cables and rechecked the power pins in the shucked drive. Nothing has changed, so your prognosis appears correct! I assume the boot options of AHCI mode, IDE mode or “no boot” mode, is not relevant? Is there a reccomended card with a 2 port Asmedia controller? Thanks again for your help.
October 31, 20205 yr Any 2 port Asmedia controller should work, as for a specific brand this is a known good one: https://www.sybausa.com/index.php?route=product/product&product_id=151
