System:

 I was able to get an old Dell T320 and I had 3 new 4TB hard drives. 2 seats Baracuda and 1 WD blue  

 

No hard drives are registered. I attached the diagnostic zip file. 

 

Any ideas?  the hard drives are in hot swap bays

Does the BIOS see them?

Yeah, I just ran a system check, and all 3 hard drives are recognized. 

 

When I F2 into system setup and navigate to Physical drive management. All drives appear.

The only storage devices being seen by unRAID are your USB boot device and a DVD drive.

I'm not familiar with your Dell hardware but I would expect the hot swap bays to be connected to the RAID controller.

08:00.0 RAID bus controller [0104]: LSI Logic / Symbios Logic MegaRAID SAS 2208 [Thunderbolt] [1000:005b] (rev 01)
	Subsystem: Dell PERC H710 Adapter [1028:1f35]
	Kernel driver in use: megaraid_sas
	Kernel modules: megaraid_sas

The motherboard also appears to have SATA ports.

00:1f.2 SATA controller [0106]: Intel Corporation C600/X79 series chipset 6-Port SATA AHCI Controller [8086:1d02] (rev 05)
	Subsystem: Dell C600/X79 series chipset 6-Port SATA AHCI Controller [1028:04fa]
	Kernel driver in use: ahci
	Kernel modules: ahci

If you can connect your disks to those then unRAID will see them, as it's already seeing your DVD drive. In order to use the RAID controller you will need to find out if you can put it into JBOD or IT mode. A quick search revealed this:

which doesn't look hopeful, but that was over three years ago.

Thanks so much, yeah i think that confirm me thinking it was something wrong with the perc controller. 

 

Can I remove the Perc completely?  or should i look for a compatible upgrade

If it's in a PCIe slot (i.e. not built into the motherboard or in some custom socket) you could unplug it and replace it with a Perc H310, which can be flashed with IT firmware. 

it is a PCI one, Thanks for your help. 

 

Update:

I swapped it out got an H310 and it works fine.
