What happened:

After a restart, my LSI 9300-8i HBA stopped showing disks. I've had the card for almost 3 years, and it seems to have just stopped working. After doing some diagnosing myself, I believe I've ruled out the hardware as being the issue, but I'm open to suggestions on further diagnosis if someone still believes it's a hardware issue.

What I've tried so far to fix/diagnose:

- I tried reseating the HBA in the PXIE slot and reseating the mini-SAS HD connectors and the SATA connectors.

- I moved some disks from the HBA to directly connected to Motherboard SATA ports. The hard drives I connected to the motherboard showed up. This ruled out the drives/disks as the issue.

- I purchased a brand new LSI 9300-8i and hooked it up along with switching out for the new cables but the drives still aren't showing up.

- I can see the "Avago Technologies MPT SAS3 BIOS" HBA screen when booting the computer, and the green light (heartbeat LED) flashes on the HBA card which seems to show that it is capable of general activity so to me, the issue is likely not the HBA card(s).

- I've read many posts here so far, but most seem to either be about the HBA never working in their initial setup, or the issues are fixed by purchasing a new card. Since I've done both of these things, I'm unfortunately unable to diagnose this issue without help.

Fun request:

If someone does find some helpful information in my diagnostics files or elsewhere, could you please include in your response where you found the information? This request is to hopefully help spread knowledge or "teach a man to fish". I attempted looking into the diagnostics files myself, but I have no idea where to start or what to look for.
Some of the places I thought I might find information but haven't are:

- tried looking in config\disk.cfg, logs\syslog.txt, logs\vfio-pci.txt, and others but didn't see anything related to the HBA.

Thank you, everyone for your help here and with past issues so far. I've had few issues with UNRAID, but when I have had issues this community has been excellent in helping me find what I'm looking for.

02:00.0 Serial Attached SCSI controller [0107]: Broadcom / LSI SAS3008 PCI-Express Fusion-MPT SAS-3 [1000:0097] (rev 02)

Subsystem: IEIT SYSTEMS Co., Ltd 12G SAS3008IT [1bd4:000c]

Kernel driver in use: vfio-pci

Kernel modules: mpt3sas

Controller is bound to vfio-pci, unbind it and the disk should come back.

Thank you for this! It led me to my issue!

I do remember there being a flag at the top of the screen before I restarted, saying the server needed a "restart for VM updates to take effect" or something along those lines.

It looks like what happened was the "PCIe ACS override" option in Settings -> VM Manager somehow changed from whatever setting I had it at before to "Disabled". This meant that the GPU I was using to passthrough to one of my VMs shared an IOMMU group with the LSI 9300-8i HBA.

I know I had this setup properly in the past, and I don't believe I changed this setting on my own, so I'm not sure why/how it happened, but regardless, it seems to be fixed now.

I appreciate your help, JorgeB!!
