November 22, 201312 yr Hi guys, Just built my first Unraid box. Have a Norco 4224 case, two 2 x SUPERMICRO AOC-SAS2LP-MV8 PCI-Express 2.0 x8 SATA / SAS 8-Port Controller Cards, and one 1 x SUPERMICRO AOC-SASLP-MV8 PCI-Express x4 Low Profile SAS RAID Controller. Running Unraid 5.0.2 Using just 2 drives to start: one 4 TB for parity and a 2TB for data. And a 250GB Samsung SSD for cache. As I migrate data from my old NAS to Unraid I will move the drives. For the life of me I can't get Unraid to see my two drives on either of the Supermicro AOC-SAS2LP-MV8 cards. Tried swapping around all six of my SAS cables to each port on each of the two cards, tried removing all cards except for one, tried each SAS plane on the Norco, and they just won't show up in the Unraid menu (the SSD cache drive connected directly to the motherboard does show up). dmesg|grep SATA|grep link shows only two drives (the SSD cache and the thumbdrive holding Unraid). If I plug the two drives into the SUPERMICRO AOC-SASLP-MV8 PCI-Express x4 Low Profile they show up fine. When plugged into the x8 cards they do appear upon boot, and the cards show them in their menus if I press Ctrl-M. Completely... Utterly... Lost... Any help would be greatly appreciated. I have attached two logs. One (syslogx4) with the 4TB connected to the x4 card and showing up just fine, and one with the 4TB on the x4 and the 2TB on the first x8 card (not showing up, but the 4TB does). If I put both on either of the x8's on any of the planes, using any of the cables they don't show. logs.zip
November 22, 201312 yr Ehm... If you swapped around the cables (it is a quite common mistake to use the wrong cables, there are 2 kinds of SAS cables), and that does not help... Google compatibilty with your motherboard.. The connectors are sometimes really meant to be used as graphics card only slot.. If that is it you are seriuously fried but you might as well know.. Also swap around the slots and try with only an MV8 in... Just to make sure its not conflicting somewhere..
November 22, 201312 yr In latest run of these cards Supermicro changed the PCI ID and the linux mvsas driver no longer binds to it. I patched the driver to correct this in release 5.0.3 which I should be posting today. More info: http://lists.debian.org/debian-kernel/2013/09/msg00184.html
