We currently have a HP Proliant dl360e gen8 server. It had 4 x 450gb sas 15k hdd's. I have removed two and replaced the two with 4tb 7k sas hdd's and built the raid accordingly. However on the RAID page and after reboot and installation of server 2012, the fan seems to be in overdrive and the amber light is blinking. When I take out the two new drives the fans are fine (even though the RAID is detecting missing drives and continued with F1.)
The drives do appear in disk management and I have created a volume but the fan noise will not go down to normal levels and am not sure where to start.
