  Yes, and it is the most likely cause. Some versions of the RE4 are validated on many PERC controllers. Many times non-certified drives will work just fine, but when certified and non-certified are running together, there are often issues ... think of it as an American, South African, and a Pilipino all speaking English - it may be difficult for the three to communicate because they all speak different versions of the same language, and this language gap can cause problems on a controller whose tolerance for error and delay (patience) are slim.
Hi, I have a raid 10 setup on a PowerEdge 2900,  Perc 6/i. There is 4 250gb drives set up as a Raid 10. One Drive failed. I tried hot swapping the drive with a newer one same size. The server crashed and rebooted, Post message showed initializing F/W and wrote Virtual Disk Degraded, but restarted Ok. When I go in to OpenManage it shows degraded and only shows 3 slots by the physical drive page. New Drive was flashing orange light on the right light indicator. Can someone help me with swapping the drive? Thank You!
