That MegaRaid is a Dual M.2 expansion card, the 9600-16i is seperate. I can seemingly purchase a pre-flashed IT mode 9500-16I off ebay (as per the link above). Based of this previous thread, the 9500-16I works out of box. However this states the 9600 should also work, as long as the OS is updated. Unsure of what's going on... I set my test drive to JBOD (which was initally Unconfigured Good and required a format) and it showed up in Unraid.

JBOD is available, though it forces me to wipe the disks. No passthrough options available. Maybe a 9500-16I pre-flashed to IT mode is the answer?

Thanks itimpi Checking the BIOS for the HBA, the drives (well the one test drive I had connected), shows up.

Through the normal BIOS and entering into the HBA settings, they show up yes (though as 'Configured Good"). I haven't checked the HBA BIOS specifically, (not super tach savvy sorry!) how do I access that? Using the old 9620-16i and configuring a test SSD to JBOD (wiping all data), it would show up in Unraid. So I don't think it's cables.

Maybe instead of buying new (and dealing with this problem), I should just go for something like this instead? https://www.ebay.co.uk/itm/134513177399?hash=item1f519c3337:g:bNUAAOSwNuljLBuN&amdata=enc%3AAQAIAAAA0KMEzesH6P178dtVmOlh0Ot9BBrgQDSzlvBAb%2FyYlbhuXhbEI8pOw1bAUw%2FXt5rTn6D7MrZuOngUGNdHHh%2FhLzfrdaR73NYgjRo9D1RMrDnk3wsjvY7yp0cF1%2FTmWm5hgiAvFQE5MdbjzasAoo77M4x%2FvV9P5lZPmjwUcwmmzvOuOZAk4NVUtK1Ab9zvFZBoHBC8YvU%2FqNHt9dgMlME1H%2BXDRztljdwgVFTThNi%2FkicreDDpl%2BElGCbnJrpdukwkTIcFCL%2F3AHKtvvJbyGd5%2FaY%3D|tkp%3ABk9SR-Ks9paNYw Pre-flashed to IT mode, 9500-16i, so still using the SlimSAS connector. Save loads of money also. It'd be great to get the other one working though... Server's been down for almost a week now and the Ebay order will take a while.

Hi again, The 9600-16i has arrived, but the disks are still not appearing. Attached are diagnostics. All drives are set to Unconfigured Good on the HBA, to avoid JBOD. Thanks monolith-diagnostics-20231214-1717.zip

Perfect, it'll arrive next week and will test then. Thanks JorgeB

Talking to my systems integrator, swapping over to a 9600-16i should do the trick? Afaik these come without RAID/JBOD meaning that they're arriving in IT Mode. Should plug'n'play?

Okay thanks Gragorg & itimpi Can you confirm whether running the card in JBOD mode would be detrimental to the performance of the server? Can't find any resources regarding Unraid, but most Proxmox & TruenNas resources state that. Leaving this HBA, do you have any recommendations of HBA's that can handle the SFF-8654 SlimSAS connector of the backplane & opto 36 drives?

Will send diagnostics soon. After tooling around abit, I was able to make the a test drive appear in UnRaid by setting it to JBOD mode inside of the 9620-16i's settings. Until then it was only appering inside of the bios settings of the HBA itself. According to this https://www.truenas.com/community/threads/lsi-megaraid-9460-16i-with-physical-drives-in-jbod-mode.80070/ setting the cards to JBOD mode (and also the disks, which formats them :/) is not great. So that leads me to what to do next. Should I return this HBA? Or do I get it flashed to IT mode (though very little documentation on that)? Or possibly just connect the backplane directly to the motherboard (need to check if the cables would fit)? If I do return it, what pre-flashed HBA should I get instead? Needs to have SFF-8654 SlimSAS connectors for the backplane (and support up to 36 drives).

Hi everyone, Just received my new production server (I run a film post production company), but none of my HDD's are appearing. Specs are: GByte S453-Z30 4U 36B Server AMD EPYC 9124 16C 2.7G OEM 8x Samsung 32G 4800Mhz DDR5 2x 3.84TB Ssung PM9A3 U.2 SSD Broadcom MEGARAID 9620-16i 4x Exos 16tb 5x Ironwolf 8tb I'm really and truly a rookie when it comes to the nitty gritty, but I'm pretty sure the issue has to do with the HBA. I couldn't find anything regarding this card specifically, but is it supported by Unraid? And if so, does it need to be flashed to It Mode? Been working all day on this, will send diagnostics in the morning if needed. Any help would be incredibly helpful! Thanks, Marcus
