We are currently installing a brand new Dell PowerEdge R510 rack server and ran in a little problem regarding the PERC H200 SAS raid controller. We startet with Debian Testing Netinstall-CD, which is a logical choice, if you have a Debian mirror in the same server room. But the installer doesn’t recognizes the raid controller.
The PCI-ID of the H200 is 1000:0072, so the controller is (according to Google) a relabled LSI Logic SAS2008 PCI-Express Fusion-MPT SAS-2 [Falcon]. You will need the ‘mpt2sas’ module for it. It should be in kernel version 2.6.30 or higher, but wasn’t on the Netinstall CD (which had a 2.6.30-2 iirc).
After a lot of searching, we eventually tried the first CD of the normal Debian Testing Installer CD-Set and it worked. The CD came with a 2.6.32 kernel. So, if you run into the same problem, you should grab the first CD of the normal installer set (which should be enough for a basic installation). The ISO can be found at http://cdimage.debian.org/cdimage/weekly-builds/.
Funny sidenote: Our Intel 10GBit CX4 NIC ran out of the box. The 1GBit onboard NIC not.
