Having trouble recognizing hard drives on new Dell PowerEdge C6105

Hey all,

I just purchased a refurbished Dell PowerEdge 6105. Got it all set up with some drives in two of the four nodes and then started running into issues.

First thing I did was try installing Server 2012 R2 from a USB drive (2.0, as 3.0 drives tend to cause issues). The drive loaded the pre-boot environment correctly. After clicking "Install," I received an error stating that a media driver is missing. No hard drives were detected by the installation but they were showing up in the BIOS. I did some searching for a SATA controller, or any appropriate drivers really, online but nothing seemed to work. All the files I found were executables intended to be used after OS install. BMC and driver redirection is working just fine (which is really cool, by the way), but nothing seems to get the drives to appear in setup.

After several hours of trying with two other IT folks until 5 in the morning, I gave up and decided to just install the OS independently of the server and then put them back in. After doing this, I booted back up and it went straight into the PXE boot sequence loop. I got back into the BIOS and, lo and behold, the drives are no longer showing up.

So, either the drives show up in BIOS but not in setup, or they are already setup and don't show up in BIOS.

Specs per node (4 total):
2x AMD Opteron 4332HE 3GHz
32 GB RAM (DDR3)
Shared 1100W PSU with 1 other node (2 total in system)
1 TB 7200RPM HGST TravelStar 1k7000
Onboard RAID, not configured/enabled
All BIOS settings default

Any ideas?

Thanks in advance!

If the drives show up in the BIOS, you should be fine as far as the mobo communication to the drive. That leaves the OS/Drivers.

Is there a setting in the BIOS, under the RAID/Storage options, that you can set to AHCI or RAID (not legacy or IDE)?

After the BIOS prompt, is there a 2nd prompt from the RAID controller that you can enter and configure options under? If so, try to disable the RAID or choose "single drive", etc...

I take it the DVD that came with the motherboard doesn't have a storage drive you can load during the Windows install? (or off of the mobo manufacturer's website).

how many drives are we talking about here? And are they going to be in a RAID configuration? Like Rapajez has suggested, if you're not using RAID, make sure that your hard drisk controller is in AHCI mode. If you are using RAID, make sure it is in RAID mode and load the motherboard RAID drivers on a USB flash, when you're installing windows it will ask you for the RAID drivers.

your symptoms tell me that the motherboard isn't set up correctly and it's expecting a RAID array when there isn't one, or it's expecting to see a single boot drive and the drives are set up for RAID. Either of these situations would cause the drive/s not to show up in the windows install screen. Furthermore if you installed the OS on the drives in RAID, windows won't boot if the motherboard is configured for AHCI mode instead of RAID mode.
