Hi Guys, 
I have been running Unraid for several years now, most recently in a Supermicro server board. The hardware has started becoming unreliable and not very power efficient, and I recently acquired a couple of R430s, which is a slight upgrade over the old hardware, and I decided to do a board transplant.

After transplanting the board and installing the HBA, however, the R430 doesn't seem to detect it, and none of the SAS disks show up. I do have one SSD that is SATA, plugged directly into the board, and that's detected, but all of my other disks are SAS drives, and none of them are working anymore. It is flashed to IT mode, and has worked fine up until now.

I tried adding "append pci=realloc=off initrd=/bzroot" to /boot/syslinux/syslinux.cfg, as mentioned here: 

But to no effect. I'm attaching my diagnostics file. I hope I haven't forgotten anything. Let me know I did. Kind of at a loss, and don't really want to have to completely undo my transplant if I don't have to!

I had just added the line to the bottom of the file, but I went back and moved it just in case that was causing it to not help. The original thread appears to be deleted, the thread I found it on doesn't really mention any specifics.

No effect after moving the line under the Unraid OS label.

This is where I placed that line.

Clarification

From lspci, the card isn't detected at all, which isn't strange since Dell is proprietary hardware, so a non-Dell card may not work. The other way around is the same thing, you have to cover/disable pins to make a Dell card work on a non-Dell server. So in this case, the solution is buy one  of the Dell HBA's.

Yeah, that's the conclusion I ended up coming to as well. After more playing around, I realized that it's never loading the HBA's bios options either.

Thanks for confirming my suspicion. I'll order a Dell branded HBA. Hopefully it doesn't freak out about non-Dell drives.
