July 13, 20205 yr hi i have an issue with my server specs b450 aurus pr motherboard ryzen 3600 32gb memory supermicro case p400 gpu 2x Fujitsu 9211-8i in it mode now the problems Fujitsu 9211-8i if i have just one raid card install the server works and plex works but i can only see 8 disks if i have 2 raid cards and one HBA on each crad i can only see half of the drives but has soon has i install the second raid card and set it to 1 in the raid controller the system start to boot shows all 11 drives in the raid bios but they dont show up in unraid and the p400 doesn't work anybody got any ideas i am assuming it is an unraid issue with the raid bios showing all the disks (but you all know what asume did) i could understand if if i could not see the drives in the bios but they are showing up. Thanks in advance
July 13, 20205 yr Community Expert You should attach your system diagnostics zip file (obtained via Tools -> Diagnostics) attached to your next post if you want any sort of informed feedback.
July 14, 20205 yr Community Expert On the diags posted I only see one LSI and it's detecting 8 disks, are those diags taken with the problem configuration?

Thanks in advance i had a similar issue trying to run 3 pci express sata cards not seeing all the ports. when running 3 pci cards if i understand it right it will run 8x slot 1 and 4x slot 2 and 3 your raid cards are probably 8x cards. i think this is the limits of the b450 chip as it only has 16 lanes from the cpu. you can skirt this by getting a 16 port mini sas or switch to an x470 board which i believe handles the lanes better and has lanes of its own to use but i am not 100% on the x470 path. your raid card probably handle more drives and their are breakout boards you can get to run more drives off the controler. i ended upt buying 4 different controllers and counting to trying and fix this i have a 16 port raid at the moment running all the drives in their own container. i just got my hba card in so i will be trying that out this weekend. if you want to pm me over the weekend ill let you know if this fleabay card from china worked.
July 14, 20205 yr Author this is the one with the second card installed and no p400 gpu or second raid card there should be a 1tb disk showing up, the disks shows on book in the raid card gui interocitor-diagnostics-20200714-1258.zip

July 14, 20205 yr Author so is that is saying the second card cannot be seen because the driver is in use ? Edited July 14, 20205 yr by andy harris
July 15, 20205 yr Community Expert Barbecue of hiding the controller from Unraid with that custom command line, it will hide any controllers/cards using those IDs, HBA is currently 07:00:0
July 15, 20205 yr Author So can I remove it it is not something I have entered or does it come from something else I am running? If I can how ?
