Hi I have a Dell 2950 with a Dell Perc 5/i

The following are the information:
Bios: 2.0.1

Raid PERC 5/i
   Tool: 1.04-019A
   Package 5.2.1.0067
   FW Ver: 1.03.40-0316
   Bios Version: 1.04-019A
----------
Currently I have 4 x 250MB drives. Naturally I am running out of space. I was hoping to use the available bays with 2 x 4TB SAS drivers to migrate to a larger space. my discs are ST4000NM0023 3.5" Drives

Now that I have put in this discs I get blinking Yellow LED on the two new discs abd disk fault error message in the raid controller menu for the two new discs.

What do I need to do to get the disks recognized?  I hope it's an easy firmware upgrade.

The PERC 5 (and 6 for that matter) do NOT support drives larger than 2TB. No firmware update will fix it - it is a hardware limitation for that controller. I have heard of people putting the unsupported H700 into a 2950 with some success, because that does support +2TB drives, but that can't be guaranteed to work in a 2950.

Great Thank you for your quick response.

Are there any other cards that is compatible to support larger disks?

There are no "supported" cards for the 2950 that can use disks larger than 2TB. The H710 is your best bet.

Or perhaps a third party RAID controller.

I meant to say H700 as the controller. The H710 is newer and may be more prone to issues on a 2950. A third party card may work, but because the 2950's storage slot is designed for PERC controllers, you are probably less likely to run into problems with a Dell controller.
