jamesp469 Posted January 11, 2021 Share Posted January 11, 2021 (edited) I'm having issues adding a second HBA card to my build. I recently purchased a CSE-836 JBOD unit online, as well as a 9207-8e and two SFF-8088 to SFF-8088 cables to connect them. The JBOD (CSE-836E16-R92JBD) has a SAS2 backplane (BPN-SAS2-836EL1). My original build has an E3-1230v5 in a X11SSM-F with a 9201-8i (in CPU Slot7, x8). I've tried adding the 9207-8e to CPU Slot6 (x8 in a x16), and while both are showing as available in the BIOS I'm still running into issues adding it to Unraid. BIOS is 1.0b. When I initially added the internal card, I recall having issues getting it working as well, and believe the solution was getting into the VFIO-PCI config to bind it to the vfio-pci driver. (though this may have been for VM access). With PCIe ACS Override enabled, I'm seeing each card in a separate IOMMU group IOMMU group 11:[1000:0087] 01:00.0 Serial Attached SCSI controller: Broadcom / LSI SAS2308 PCI-Express Fusion-MPT SAS-2 (rev 05) IOMMU group 12:[1000:0072] 02:00.0 Serial Attached SCSI controller: Broadcom / LSI SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] (rev 03) When I've attempted to Disable the ACS override, the system wouldn't see any of the drives connected to the original card. When I tried binding both to the vfio-pci driver, I didn't see any of the JBOD drives. Not entirely sure where to go from here, any help would be appreciated. Thanks in advance. unraid-diagnostics-20210111-1539.zip Edited January 12, 2021 by jamesp469 more sys info Quote Link to comment
JorgeB Posted January 12, 2021 Share Posted January 12, 2021 One of them is bound to vfio-pci so it's not available for Unraid. Quote Link to comment
jamesp469 Posted January 12, 2021 Author Share Posted January 12, 2021 Thanks, that's exactly what it was. I forgot I had removed a GPU to put this card in, and that GPU was being passed through to my VM. All set now! 1 Quote Link to comment
