This has been fixed in the latest releases.

In case someone finds this. 1. You can run 4 drives from the backplane to the SATA/8087 port on the Mobo. Swap the optical for an SSD and run it fine with no additions. 2. Caddy swap works fine. Auto detects in #1 above. 3. After flashing my perc h310 to IT mode. I ran a comparison with the s110 onboard non-raid passthrough then after the flash ran it again on the IT mode h310. For some reason I expected them to differ but in fact they were nearly identical.

That worked. Thank you.

Hoping a new config works. Been reading about it. Ill have to figure out how to do this without the breakdown cables for the backplane

Currently I am running 6.7.2 unraid & recently installed a perc h310 but now the drives show as missing/wrong. I built the array using the integrated s110 (non-raid) so I had 1 Parity and 3 Storage Drives. After adding the perc h310 running passthrough the drives so that they are unable to be matched in the main tab of unraid even though I have the serials matching thus not allowing me to start the array. I ended up moving the first 4 drives back to the s110 and added more drives to the h310. How do I go about getting everything on the h310 without having to rebuild from scratch?

I'm dumb. Was looking all over for this: https://github.com/Radarr/Radarr/issues/3562

Thank you! I posted some pics above.

Appreciate it. I have googled a bit and the search on the forums is not the greatest. I had some questions because the way the board is configured did not make sense. The backplane plugs straight into what appears to be a sata a-d plug on the motherboard. My assumption is that disk 0,1,2,3 can run without a perc in the sata a-d slot, while 4,5,6,7 will need some sort of controller. There are also 2 SAS plugs for SAS-A and SAS-B on the backplane that go straight to the motherboard. Can I run these as regular sata and bypass the need for a perc?

Hi Everyone, I am new to unraid. Just booted to the OS for the first time tonight. I recently acquired a Dell r520 from a 'friend' and had a few questions running unraid. 1. The perc was removed from the server. I have the bios set to run ahci (not raid mode). Can I just add nas drives to the caddys --> the backplane then configure those in unraid OR do I need to buy myself a raid controller? I am familiar with how unraid works and the fact that you DO NOT need a raid controller. My question is whether I need the perc for this to even work. 2. Cache Drive: My plan is to remove the DVD ROM and add a caddy with an SSD for this. Does this seem like the right plan? 3. Any suggestions for running unraid on this server? Thanks, X
