This weekend, I replaced my motherboard, CPU, and RAM. I also took the opportunity of the server being down to update the HBA card's firmware version to v20, and ensure that it was in IT mode (from what I could tell, it was in IR mode prior, but still working fine; probably shouldn't have messed with it, but hindsight and all...).

However, when the computer restarts, randomly, some drives will not show up, making the array invalid. The missing drives seem to be random, its like they're not awake enough to be seen by Unraid. But I am obviously concerned that I messed something up.

If I run for h in /sys/class/scsi_host/host*/; do echo "- - -" > "${h}scan"; done then the drives show up. And I can start the array and everything. I haven't tried starting Docker/VMs while I mess with all of this. (I'm also adding an NVMe drive for my docker containers, and replacing the cache drive with a Samsung SATA SSD).

There's also a bunch of "Historical Unassigned Devices" listed at the bottom and I'm not sure what to do with them, forget them, etc?

If it helps, I did have trouble booting with the new motherboard. It would only boot to a black screen. Fully up to date BIOS.

Ended up finding someone else who had this problem on a forum that changed their bootloader to something else, and that allowed me to finally boot into Unraid.

Specs:

AMD Ryzen 9 9900X
Crucial Pro DDR5-6000 CL36 (2x16GB)

MSI X870E-P Pro WiFi

Noctua NH-D15 Black

LSI SAS 9210-8i

HP SAS Expander PCI-E 468405-001 487738-001

Please let me know if there's any other information I should add, and I'll be happy to. Thank you for reading.

Don't see any errors logged, suggesting more of a BIOS/firmware issue or some other hardware compatibility problem, try testing in a different PCI slot if possible.

This seems to have been resolved by re-flashing the HBA card without the supplementary BIOS files. In my case, using these as instructions: https://forums.serverbuilds.net/t/guide-updating-your-lsi-sas-controller-with-a-uefi-motherboard/131 and running only these commands:

sas2flash.efi -o -e 7
sas2flash.efi -o -f 2108it.bin
sas2flash.efi -o -sasaddhi XXXXXXX

[replacing the XXXs with the address on the sticker on the card].

Since flashing it without the -b x64sas2.rom -b mptsas2.rom switches, I've had no issues with this part.

Can you confirm that remove bios, efi from lsi solve the issue?
