Hello. I have an LSI 9211-8i controller which is running the IR firmware. My intention is to flash it with the IT firmware and use it for an md RAID array. However I don't think it is playing nicely with my motherboard BIOS. On first installing it, with no drives attached, the LSI BIOS runs and then the motherboard BIOS goes through an AHCI drive detection phase. After detecting the drives (2xHD 1xOptical, connected to SATA ports on MB) the boot hung and required a hard reset. The LSI MPT2BIOS version is 7.29.0.0 and the controller firmware is 15.0.0.0-IR. The motherboard is a Gigabyte GA-MA78G-DS3H (revision 1) running the F3 BIOS. I can enter the LSI configuration utility during the controller boot process and I see that it has a PCI slot of 'ff' which, according to the utility, indicates an invalid PCI slot. I've updated to the latest motherboard BIOS (F9) and now the boot process follows the same sequence but continues after the AHCI detection and eventually brings up linux. However the controller still reports a PCI slot of 'ff'. I can see it in linux but if I have a drive connected I don't see it in the boot configuration utility (not sure if I should) and I don't see it as a /dev/sd? device (not sure if this is where I should find it). So I suspect it's not really working. Here is the output from lspci -v: 02:00.0 Serial Attached SCSI controller: LSI Logic / Symbios Logic SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon] (rev 03) Subsystem: LSI Logic / Symbios Logic Device 3020 Flags: bus master, fast devsel, latency 0, IRQ 18 I/O ports at de00 [size=256] Memory at fdcfc000 (64-bit, non-prefetchable) [size=16K] Memory at fdc80000 (64-bit, non-prefetchable) [size=256K] [virtual] Expansion ROM at fdb00000 [disabled] [size=512K] Capabilities: [50] Power Management version 3 Capabilities: [68] Express Endpoint, MSI 00 Capabilities: [d0] Vital Product Data Capabilities: [a8] MSI: Enable- Count=1/1 Maskable- 64bit+ Capabilities: [c0] MSI-X: Enable+ Count=15 Masked- Capabilities: [100] Advanced Error Reporting Capabilities: [138] Power Budgeting <?> Capabilities: [150] Single Root I/O Virtualization (SR-IOV) Capabilities: [190] Alternative Routing-ID Interpretation (ARI) Kernel driver in use: mpt2sas Kernel modules: mpt2sas Anybody run into this or have any advice? Is this really a problem? I'm reluctant to risk bricking it during a firmware flash if it truly is misbehaving.
