We have been running a few of these servers with only a 500GB 6GB SATA 7.2K drive installed with all VM's (Hyper-V) sitting on an attached SAN.
For various reasons we needed some local storage on the server and installed 2 1.2TB SAS drives (10K 2.5"). They hot installed okay but the server had to be brought down to enter the MegaRaid software to configure the RAID.
Unfortunately with the drives installed, the server won't boot past the initial BIOS screen and certainly doesn't get to the RAID screens.
Does anybody have any idea why this would happen? Is there some BIOS update required to support these drives and/or MegaRaid software upgrade?
The servers are up and running at the moment so I can't find the version of the RAID software running.
Thanks
Larry

Did you check the LOM and PCIe Slots Configuration Parameters (BIOS --> Advanced)? IS this particular slot enabled?
Also check the following regarding faulty LSI RAID controllers.....

Hi Lauren,
If you don't have a PCI or a mezzanine based controller and you are using the embedded raid controller you need a chip for the embedded raid controller to support SAS drives. By default the embedded controller only supports SATA drives. See page 9 of the link below
Please let me know if you are not using the embedded controller
