Hello all,

I'm currently facing a very annoying and just pure headache inducing situation

I'll give the rundown here of what my use-case is, just so if anyone wants to they can give me better ideas as to what I can improve and maybe give tips.

Currently I'm wanting to run a server with bulk storage (in this case 4x HGST 4TB) this will in ideal circumstances be in a RAIDZ2, since they are refurbished drives. My idea is to run proxmox on bare metal, and on top of that run Truenas Scale for bulk storage and have a VM for docker containers and one for Pteradactyl and Roon server usage on a faster 500gb SSD.

Now for the problem at hand:

I bought an LSI 9300-16i of off Amazon and flashed it with IT mode firmware 16.00.20.00. I connected all the drives to the HBA with a MiniSAS to SATA breakout cable, and connected 2 drives to SATA power directly and 2 with Molex to SATA (I understand the risk). The drives connected do not show up in the HBA bios nor UEFI or Windows. the HBA does show up in windows and can be looked through with MegaRaid Storage Manager. in here it also shows 0 drives available, I applied the 3.3V fix and that didn't help. The 2 drives that are connected to SATA power do power on and feel warm to the touch, the ones powered with the Molex to SATA adapter aren't being powered on for as far as I know (I will look into that later)

Specs, for if someone needs it for compatibility reasons.

Aorus ELITE WIFI 6E

Ryzen 9 9900X

Crucial 48GB DDR5-5600

Powered by a 550W PSU I reused from my own PC build.

4x 4TB HGST 7K6000 drives.

9300-16i Amazon link:

HBA Card SAS Controller, 9300 16I HBA Card, 12Gbs SATA SAS 16 Ports HBA Controller Card, for Linux, for VMware, for FreeBSD : Amazon.nl: Electronics & Photo

I'm at the end of my knowledge and research capabilities. and really am in need of help, thanks in advance!

(Sorry for any grammatical mistakes, English is not my first language)

MiniSAS to SATA has forward breakout and reverse breakout cables...

Are you sure you used the right type of cable (forward breakout is what you need)? The fact that the HBA doesn't show any connected drives, rules out any Windows issues.

Alright! Thanks a lot for the information, I will order a new cable today and hopefully this will be the thing that fixes it

Hey i'm now just noticing that these cables that I bought should be Forward breakout cables. They say MiniSAS (Host) and SATA (target), so now i'm even more confused as to why it isn't working
