The first thing I would look at is drive compatibility. Would you clarify the part number for the 2 TB drive and I can check that for you. Also I would consider updating the 2950 on BIOS, Drac/BMC, and specifically the raid controller itself. If the drive itself is indeed compatible, you may want to see if the drive has a firmware update available as well. You can also Private Message me the svc tag for the server as well and I can look into the servers specifics.
